...well, you know the phrase, overused as it is. However, the song remains a classic, especially when sung by Kermit the Frog. The Muppet Show was a constant fixture in my home in the 1970s, and violinist, whistler, singer, and multi-instrumentalist Andrew Bird is a constant fixture on my CD player and iPod today. So when Mr. Bird covers Mr. Frog (that’s a strange ecosystem...) for a forthcoming Muppets tribute album, I sit up and take notice. So for a little Going Green entertainment on a hot summer afternoon, click on over to NPR to read an interview with Mr. Bird and listen to his cover of “Bein' Green.”
