Thanks everyone! I got really lucky with this one. I figured the second clip was from Fall 95 (I was originally thinking a Bowie) and tracked it down without too much trouble, then used the Pete's hint that the theme had been used before to narrow down what I was looking for. I figured first clip was from pre-95, so started my search at 12-31-94 and was instantly rewarded. The third was the most frustrating. I had no idea on an era so was searching sporadically using the jam charts. I eventually reasoned that the first two were from '95 (+1 extra day) so I should focus my search there and was rewarded.

I'll definitely miss taking part in these (most) every week! Its been fun and as @lysergic said, I'm always getting turned onto new jams through MJM.
