Over and over I keep singing the refrain "I'm the Pied Piper, follow me" and even my cats have started to cover their ears with their paws! The song is in a commercial that I seem to hear every day, so just when I think the tune has escaped my brain, it quickly returns. English singer Crispian St. Peters recorded "The Pied Piper" in 1966 and it keeps finding new life, including on the show "Silicon Valley." Here's St. Peters "performing" on TV in the 60's, complete with campy audience participation. (photo: Getty Images)
