Almost Famous (2000)

In director/writer Cameron Crowe's semi-autobiographical film:

• the uplifting scene of the Stillwater band (mythical) on their tour bus singing along to Elton John's "Tiny Dancer" playing on the radio
• the scene on Stillwater's chartered airplane when lead guitarist Russell Hammond (Billy Crudup) began singing Buddy Holly's "Peggy Sue" when the aircraft hit heavy turbulence
