I poked around the Internet a bit and found that The Clash and The Cramps were together for at least one concert. http://www.lookatstubs.com/bands/the_cramps.htm Other than The Clash, I will try to stick with the bands/groups that had at least one appearance with The Cramps and didn't achieve massive fame.
The Clash with Bo Diddley & The Cramps - The Palladium (New York, NY) - February 17, 1979 Also found that The Clash really liked Bo Diddley and requested for him to be there. One of the songs by The Clash borrowed/sampled from Bo Diddley.
Another song that borrowed/sampled from Bo Diddley was I Want Candy. Bow Wow Wow did well with their cover of that song.
Now that the Bo Diddley part is completed, will switch to the bands/groups that connected with The Cramps in some way decades ago. Not to much in the way of Heavy Metal or Grunge, so a decent variety of music to listen to.
