There where 3 Different Openings to ycdtotv the original was with the 1 hour live show in 1979 and there was also a spinoff show called Whatever Turns You On witch was basically the same idea as the yctotv series that would follow. Then in 1981 the series came back and was picked up by nickelodeon and it got a new opening part of was taken from the wetyo op. then in 1882 they changed it again to what is known to be the main opening from 1982-1990

I thought it would be nice to see all of them one after another. (less info)
