It started in high school for the Plain White T's. They jumped from covering Weezer and Green Day songs to being a full-fledged band that has grown in both popularity and maturity through their years together.
Vocalist Tom Higgenson's basement, or "The Pad," was where all of the magic began. After covering various punk bands for a while, he began to write music of his own - introducing it to his musically inclined friends, they officially formed The Plain White T's in 1997.

""Hey There Delilah" was on MySpace and it just took on a life of its own. Every comment we had was like, 'Oh my God, "Hey there Delilah" is such a good song.' Everybody's profile that we'd go to used that song on their
