Tony Kanal/ Gwen Stefani/ Adrian Young/ Tom Dumontt
Also Gabe and Stephen (the ska section)
Eric Stefani (Yes, he's Gwen's Bro) wrote lots of the songs on ND's albums but he left the band to be a cartoonist (Which he is on the Simpsons). He drew all the cartoons in the self-titled album.
Special thanx to No Doubt and their awesome web page!
