Ron's a great songwriter! Check out the McCartney-esque bassline on "Michael and His Dad" from Long Player - Late Bloomer!
I always felt Paul should do a couple of covers of Ron's material since they both have very similar styles / sounds / vocal ranges, and Ron has an incredible number of great tunes for Paul to choose from (and vice versa, obviously). I think I even mentioned this topic on this messageboard 4 or 5 years ago. As a side note, Ron once had breakfast at Paul & Linda's place back in the 90's. I think Ron was hanging at the house of Chris Difford who lived near Paul and one morning got invited 'round for breakfast. Not sure what they ate but pretty sure it wasn't bacon! Peace!
