Still no luck finding Tommy Gear. Leads via Kristian Hoffman of The Mumps and Vaginal Davis have been fruitless.
Jeff McGregor is also off the radar even though his acclaimed solo project The Solipsistics has a minor, though obscure, web presence. I'm trying to make contact through his former Snot Puppies bandmate Kevin Hunter (now with Wire Train and Bella Nova).
On the positive side, I've made contact with a friend of a friend of David Braun, which looks hopeful.
