Knockin on Heaven's Door Joke

[gasgage]

I happen to catch the last thirty seconds of this song on 97.1 Talk radio station in Los Angeles.  It was played around one in the morning on some comedy show.  The song was Knockin on Heaven's Door sounding a lot like Guns N Roses except it had different lyrics.  I think the lyrics were:  

Chorus
Welcome to the Betty Ford (instead of Knock Knock knockin on Heaven's Door)

The song also had a line in it about putting down a folding chair.  

I was caught off guard so the song trick me at first because it sounded like Axl.  I thought it might be a new GNR song.  Then I started hearing the music of Knockin on Heaven's Door and I was kind of pissed because I thought it might be there first single off Chin Dem and it was just a rip off of an old song with different lyrics.  I then started hearing the lyrics and realized it was just a joke.  It was pretty funny but I didn't here much of it.  Has anyone else heard this song?  I would like to hear the whole song.
