For 'Man or Muppet,' they wanted a song about being a man or a Muppet. [...] I really wanted to do a power ballad tune. And just wanted it to be as dramatic as I could possibly get it to be. [...] I was really influenced by Harry Nilsson's "Without You" and Eric Carmen's "All By Myself."
Prompted by the host, McKenzie sings a bit of "Without You" and says "Harry Nilsson's got the best voice ever."
He sang that at the height of his career just when his voice was still there before he started partying like a maniac with John Lennon.
