- "Chuck, Chuck! It's Marvin! Your cousin, Marvin Berry! You know that new sound you were looking for? Well listen to THIS!"
- —Marvin Berry on the phone with Chuck Berry, while Marty plays Johnny B. Goode.
After finishing a set, Marvin and the rest of the band went to their car for a smoke break. While in the car, Marty was thrown into the trunk by Biff's gang. The trunk was closed with the keys inside. Marvin, in an effort to free Marty, badly cut his hand with the screwdriver he was using to open the trunk. Marvin was unable to play the guitar for the rest of the night.
Marty gladly played the guitar for the band. After singing "Earth Angel", Marvin asked if Marty would like to do one more number; something that "really cooks". Marty agreed to play one more song and chose "Johnny B. Goode". Initially impressed, Marvin called his cousin Chuck so as to allow him to hear the "new sound". By the time Chuck was listening, however, Marty had segued into playing heavy metal, a "new sound" that nobody was quite ready for in 1955. (What Chuck thought of the "new sound" remains unrecorded.)
Marvin was somewhat bewildered as Marty handed back the guitar.
