Slim Jon,
A small correction to your collaberations page for Brian Setzer. Brian or course did play on the Mystery Train cd 706 Union Avenue on the song Don't Say Goodbye. By the way, Brian only played the second solo on Don't Say Goodbye.
The song "Rockabilly Smash" does not feature Brian playing guitar, but, Brian did let Michael Ubaldini play his "Steve Miller" given 6120 on that entire song.
I had a chance to talk with Michael Ubaldini just after his CD 706 Union Avenue was relased and he told all about it.
So Brian does only play the second solo on Don't Say Goodbye, but his 6120 was used by Michael on Rockabilly Smash.
Have a Gretsch Day !
