No Kevin, I think it's one of the 2 you already know. My home address book always shows Hovering Bob before Bob H on account of alphabetically Ham precedes Haw.... Bob H is the one who used to share a lab at Marconi with Mr Vernon, and run PA rigs at festivals, and who still goes out with the Herga Mummers on Boxing Day...
On the other hand, Bob Williams is a Mudcat member too....
I can't help with a ticket though! George Simmons is trying to find one too....
