He's awesome from all accounts. His appearances on Enterprise as Admiral Forrest were great alone, (sorry they killed him off really - twice!), but considering the few Klingons, Romulans, Cardassians, and even a Borg he played... I don't attend the convention circuit much, but there should be no shortage of questions to ask while asking for an autograph. He must hold some kind of record for playing the most number of characters in Star Trek.
Enterprise Blues Band is their name with Casey Biggs (Damar) , Richard Herd and Nathan Philips joining them on occasion.
