I was watching some special on AFI's 100
best Movie Songs and saw a clip from a
movie but missed the title.

The clip shows some guy (actor was named Tom---maybe Cruise? or Hanks?)
dancing in his underwear to a Bob Seeger song.

What is the title and star of this movie?

Risky Business - Tom Cruise

(suddenly I feel really old )

That's what I thought. Probably should rent that again in the future.

Thanks Cow.
