Axis of Awesome
Just wondering if anyone has ever heard of this group. My son, who likes to sing, "introduced" me to them when he and a few friends were attempting to do the 4 Chord Song. Since that time, he's entertained us while travelling in the car. Granted, he messes up a few times - forgetting which song comes in what order especially now that they updated their original.
Anyway, here's the youtube link here of their original -- well I think it's their original. It's the one my son first showed me. I enjoy his doing A Ha's Take on Me portion the best cause I love to hear him hit that really high note.
Apparently they have their own youtube channel here
