Yep, that's a tattoo alright. Doughty used to sing and play guitar for the way underrated '90s band Soul Coughing. Now he's a solo artist who just released an album, Golden Delicious, earlier this year.
Here's a Soul Coughing video from 1998. Think about the musical wasteland of the late '90s, and then think about how this band managed two big-time, MTV-video hits ("Super Bon Bon" and "Circles").
