So like

Family Force 5

Do you guys know them?

The lead singer's name is "Soul Glow", and two of the members are his brothers. The drummer, his brother, is "Crouton" and the bass player (I think) is "Fatty" his oldest brother. The guitarist is "Chapstick" and the tiny piano thingy player is "Xanadu" at least, I think that's his stage name.

I freaking love them. Their old songs are my favorite but I really like their new CD XD 

Ever heard of them? XD
