Kenny Brack

Whatever happened to Kenny Brack?  He came back from his terrible injuries, qualified like a mad man at the 2005 Indy 500 and then disappeared?
"For us, we certainly would have had Kenny in a car if the sponsorship was there or what have you," said former Indy champion-turned-car owner Bobby Rahal.  "It hasn't been a matter of us not wanting to bring him in, not thinking he was ready; it was a matter of there not being a situation there, an opportunity."
This from the Kenny Brack page on Wikipedia:
As of 2006, Brack lives in Belgium and has retired from open wheel racing. Brack spends most of his time currently as the lead member of a rock band.
