You want some real Back to the Future/Guitar geekery
The guitar that Marty plays at the dance is a Gibson ES-345, which wasn't introduced until 1958. The pickups in the guitar wouldn't have been invented until 1957.

There is only Monty, and those desperate enough for companionship that they talk to him.

I suspect it was because the 'joke' was that it was Chuck Berry's cousin in the band.
And Berry is associated with ES-335s & 345s.
They should have used a ES-350T

I've never found tangles more attractive than I do right now.
