Unfortunately, for the "official" records, I don't know who the actors are impersonating the various big musical acts of that time in this video. But be prepared to see the following:
CYNDI LAUPER'S MOM
There may be others who are either too generic to be anybody in particular, or I just didn't recognize who they were supposed to be. (Specifically, the heavy metal band whose guitarist catches on fire.....)
As for its placement in the TV Universe, I'm leaning towards the TV dimension of Skitlandia, just for the framing device of the Dave-TV studios. This is not a blanket placement for all music videos with storylines, however. There is a musical TV dimension from which the demon Mr. Sweet hails. (The TV Crossover Hall of Fame member was seen in an episode of 'Buffy The Vampire Slayer'.) As an example, I'm thinking of the video for the song "Smuggler's Blues".
So without further ado, it's time to present David Lee Roth and his version of:
"JUST A GIGOLO"/"I AIN'T GOT NOBODY"
A big Toobworld thanks to J.r. Klink, a Facebook friend, for featuring this video back on Roth's birthday, but from a different video resource. (I just find YouTube less complicated to use.....)
