Trademark style: Hippy! Think of those long locks of hair.

Best lyric: Mmmbop, ba duba dop / Ba du bop, ba duba dop / Ba du bop, ba duba dop / Ba du / Yeah / Yeah" — "MMMBop!"

Where they are today: Their long locks may be gone, but this brotherly trio is still going strong! All three brothers are married and have kids. They released their fifth studio album in June 2010 and are currently on their Shout It Out tour.
