Here is Howie Mandel, the host of NBC's "Deal or No Deal", long before he became the host of that series, in a classic medical series that, oddly enough, aired on the same network as "Deal"-- NBC's 1982-88 medical series "St. Elsewhere". The following are links to pages that contain title sequence clips from that series. (Scroll towards the bottom of the mentioned pages to find these clips.)

http://www.tv-timewarp.co.uk/video_intros/drama01.htm (The S1--1982-83--title sequence is there. The clip is 3.72 MB, and the arrangement of the opening theme in it sounds really cool, at least to me. The clip is also very high quality. Also, the title and cast member names are in a different font than what would come later.)

This clip is 7.15 MB, and has very jumpy video quality, unlike the one from TV-Timewarp).

The clip is listed on the page as being from 1983, but I believe that this is from the 1986-87 season, due to the fact that Bruce Greenwood, Bonnie Bartlett, and others are in it, as well as Mandel. This is a 540 KB Real file.)
Although I do not have any clips of Howie in action from the series (his role was that of Dr. Wayne Fiscus), I do believe that you will like seeing what Howie looked like when he had hair, unlike today.
I really do hope you enjoy them!
