This Purchasing Rockstar strip basically happened, unbidden, during a phone call to Rick Betschen of JRB Machine Tool. The first two panels are a nigh-verbatim transcript of our conversation. Rick is an actual rock star, in that he knows how to play the guitar and has played in bands. That’s more than one band.
Do you Google+? There is a “making of this strip” album on my Google+ account page thing.
