I remember Doug and Al Cromwell very well indeed. As a matter of fact, a friend of mine just made a CD of the two of them, and solos, from an old treasured tape I had many years ago.
If anyone can provide me with contact information for Doug (Al died in 1995) - I will happily send them the CD.
Doug Bush later took the name of his bio dad - Johnston - and I'm not certain which name he finally settled on.
