These are two videos I found inspiring today.
The Bay Area's own Ramon and Jessica (a.k.a. Dina Maccabee) sing about, and to an SF parking meter in the a cappella "Meter Maid":
And a wonderful video of a Paul Simon fan named Rayna who was called up on stage in Toronto to sing "Duncan" with the whole band. Paul just tells her to keep going. She's in heaven.
