Cat Stevens released his groundbreaking album Tea For the Tillerman 50 years ago, and to mark that anniversary he has recreated the album with some new lyrics and new instrumentation. Stevens, now using the name Yusuf Cat Stevens, played his new version of "Wild World" for Stephen Colbert on Wednesday's Late Show, and if the new version sounds similar to the old, wait until the end of the first chorus, at about the 1:30 mark.

The new album, Tea For the Tillerman 2, also has a new cover, Stevens explained to NPR's All Songs Considered, and a version of "Fathers and Sons" in which he sings with himself 50 years ago. "Essentially, the song lives in these two kinds of universes," he said. "There's the son and there's the father. And right now, you're going to hear me singing the whole song except for the son's part because the son is going to be me, which we've lifted off a recording from the Troubadour and back in 1970. So, you got me like 50 years ago singing with me today. Wow."
