Soler, I can't quit you! Just when I thought I had scoured every last corner of youtube for their interviews, covers, gigs, I uncovered this gem. The song is 陪我飛 ('Fly with Me') and was written to support kids who don't have the opportunity to go to school. Bless. The video below is from a March 2007 performance but also check out another appearance from around that time. The guys looked a bit - a lot - scrubby just a few years earlier, though surely the song makes up for any sartorial failings. Anyway, age and experience seems to have sharpened them. (Last.fm has a clearer version + free download!)
