Hellman’s “Sing For A Sandwich” Activation
Hellmann’s set out to activate its latest campaign with a bold, street-level experience in Manhattan. In partnership with TH Experiential, the brand launched “Sing For A Sandwich,” a mobile karaoke pop-up designed to engage the public in a memorable, participatory way.
The concept was simple and high-impact: step up to the mic, perform “Sweet Sandwich Time,” and earn a free Jimmy John’s sandwich featuring Hellmann’s mayo. The objective was to create a highly visible, shareable moment that reinforced brand personality while driving direct product trial.
THE CHALLENGE
The campaign needed to accomplish three goals simultaneously:
Capture attention in one of the most competitive advertising environments in the world
Encourage spontaneous participation from passersby
Deliver a seamless, high-energy experience from inside a mobile footprint
Manhattan streets offer scale and visibility, but they also present operational complexity. Foot traffic is unpredictable. Noise levels are high. Space is limited. Equipment must be reliable, fast to deploy, and visually compelling enough to stop people mid-commute.
The activation also had to feel polished and brand-forward, more than a novelty stunt. It needed to function as a fully immersive stage, capable of supporting live vocals, video capture, and dynamic lighting in an outdoor, mobile environment.
THE SOLUTION
Panavid served as the technical lead, designing and delivering a fully integrated mobile production system that transformed the truck into a reliable, street-level karaoke venue.
The goal was to create broadcast-level impact within a compact, mobile footprint, while ensuring continuous operation in Manhattan’s demanding environment. To achieve this, Panavid deployed a discreet control van nearby, staffed with crew to monitor and manage all systems in real time. This separation of stage and control ensured uninterrupted performances and immediate technical oversight without disrupting the audience experience.
Audio
A Yamaha DM3-D digital mixing console provided compact but robust control over vocals and playback. The Shure Axient Digital wireless system (AD4Q receiver with AD2 handheld transmitters) ensured stable RF performance in a signal-dense urban setting, eliminating dropouts and interference.
For reinforcement, d&b 16C column speakers delivered focused coverage toward the street, supported by a d&b CCL-SUB subwoofers to add low-end energy that attracted attention from a distance. d&b E8 speakers served as monitors inside both the truck and control van, maintaining mix consistency across environments. Crew coordination was maintained through the Hollyland Solidcom M1 full-duplex wireless intercom system, enabling seamless communication throughout the activation.
Video
A switching workflow built around the Panasonic AV-UHS500 4K switcher and Blackmagic ATEM SDI Extreme ISO allowed flexible live switching, recording, and multi-display output. Discreetly placed Marshall CV502-MB mini POV cameras captured dynamic angles without interrupting participant flow.
Inside the truck, a Sony 55” BRAVIA 4K HDR professional display functioned as a confidence monitor for singers. Outside, two Sony 75” BRAVIA 4K HDR displays projected performances to the street, ensuring visibility even in daylight and drawing crowds from across the sidewalk.
This system extended each performance beyond the truck, turning individual participation into a shared audience moment.
Lighting
Astera Hyperion and Titan Tubes, controlled via an ETC ColorSource 20 lighting console, delivered dynamic, brand-forward looks that reinforced energy and visibility. Inside the truck, Fiilex P360EX and P180 fixtures provided clean, camera-ready illumination that flattered participants and supported content capture.
Each component served a clear purpose. Audio quality ensured participants felt confident and supported. Lighting and displays created spectacle, signaling that something exciting was happening. Camera integration allowed the moment to extend beyond the live performance, supporting social amplification and brand storytelling.

THE RESULT
“Sing For A Sandwich” transformed an everyday Manhattan sidewalk into an interactive karaoke stage.
Hundreds of participants stepped up to the mic, performed in front of live crowds, and left with product in hand. The activation generated:
High visibility in dense pedestrian zones
Sustained audience engagement throughout operating hours
Direct product sampling tied to a memorable brand interaction
The combination of performance, spectacle, and reward created an experience people chose to participate in—not simply observe. The truck’s production quality elevated the activation from a giveaway to a true branded event, reinforcing Hellmann’s personality as bold, playful, and culturally engaged.
Most importantly, the campaign delivered what experiential marketing is designed to achieve: real-world engagement that converts attention into participation, and participation into product connection.
