which doesn't make a lot of sense. But it was a bar. It had a big TV set going ya-ta-ta ya-ta-ta in three glorious colors, and a jukebox that tried to drown out the TV with that lousy music they play. Anyway, it wasn't a kid hangout. I kind of like it. But I wasn't supposed to be there at all; it's in the contract. I was supposed to stay in New York and the New England states.


It seems to be the case; however, I wonder if it is correct since he never used the word jukeboxes (he only used the word jukebox).
Yes, in this register, 'they' is fine, and it does refer to 'jukeboxes [of that kind]'.
thank you
