Outside of Dan Reed, the members have appeared in only a few other videos.

Dan is the most prolific, in two videos. Blake & Dan Pred feature in one (not really a promo video), and Melvin features in one. I've not seen any sign of Brion in a video - unless you caught the TNN Edgar Winter special in August 2001 or on David Letterman in September as part of Babyface's band.
