Axis Of Awesome Updates 'Four Chord Song' To Include 'Double Rainbow' Lyrics (VIDEO)

Our lives were changed forever when we first heard the great comedy rock band Axis of Awesome's "Four Chord Song," which humorously proved that every popular song from John Denver to Lady GaGa uses the same four chords.

Now, for the Red Nose Day Telethon on BBC, the band performs an updated version of the "Four Chord Song," complete with lyrics from the hit about the "Double Rainbow" guy. If you haven't heard it yet, you'll be amazed at how well they tie everything from Red Hot Chili Peppers to MGMT and "Auld Lang Syne" together.

You may also remember the Axis for the hilarious parody of loves songs they did for Valentine's Day this year.
