FLY ON THE WALL: BEHIND THE MUSIC
by Tim Meltreger
If it's remarkable that the Psych theme marks the first time in television history a show's creator has penned and performed its theme song, it's miraculous that "I Know, You Know" was ever recorded at all, because the story of Steve Franks and his band, The Friendly Indians, is harrowing by any standard.
That statement isn't very acurate. The show's theme song is not the first in television history to be penned and performed by its creator. The theme song to the Fresh Prince of Bel-Air was written and performed by Will Smith, the show's star and co-creator.
