The One After Ross Says Rachel - S5-E1
Question: After we come back from the break, with Ross asleep on Monica and Chandler's lap, the riff that plays in the background is really familiar to me. I know I can play it on guitar and the name Robben Ford springs to mind. Has it been in a film before or is it taken from a full length song?
Answer: Ironman by Black Sabbath.
Is it the one playing right after the parents leave and there's a shot of the plane? Doesn't sound like Iron Man to me.
