"Baba O'Riley" by the Who…YESSSSSSSSS!!!
Roger Daltrey's harmonica solo in this live version at the end just puts it over the top, in a good way. Love how Pete Townshend is flopping like a rag doll during the solo, and John Entwistle is like "I couldn't care less," despite playing awesome bass guitar. Good to see Keith Moon playing his massive drum set too.
