I've saw the episode where DJ was given the boy her first kiss. This is a great episode was shown on ABC Family earlier tonight. The music was playing in the background was the instrumental version of Madonna's "Crazy for You". I have that song from the album, "The Immaculate Collection".

I found this picture off of Ebay of the 45 RPM sleeve of that song which was featured in an episode of "Full House". This is the one I don't have.
