John Cafferty and the Beaver Brown Band
In a gag from S7E6, "Tales of a Third Grade Nothing," Emperor Palpatine requests "On the Dark Side" by John Cafferty and the Beaver Brown Band.
The Rhode Island band reached the height of their popularity in 1983 with the release of the movie Eddie and the Cruisers, to which they contributed several Bruce Springsteen sound-alike tunes, including "On the Dark Side" and "Tender Years." They continue to tour as of 2021.
John Cafferty is the cousin of Family Guy executive producer and head writer Danny Smith.
