In Roadhouse Brad Wesley offers to buy the firefighters a drink after they tried to save Red Webster's store.
The house band at the Double Deuce bar is led by the lead singer and guitar player named Cody (portrayed by the late, great Jeff Healey). Brad calls him "Elvis" on two separate occasions during this scene.
It's like a morgue in here. Play something Elvis.
Elvis, play something with balls.
Why does Brad Wesley call Cody "Elvis"?
