Actually, he had a hard time saying his name as a small child, and IA was born out of "Mattias". We were dining at Goodstone last year when a sales rep from GC started talking to him, and couldn't get a grip on his name. Finally IA broke down and said "Just call me Matthew....."

The last mail I got from Glenn, I have at home, but IIRC the clinics are back to back on from noon to 1:00pm (drums) and 1:00 to 2:00 for guitar.
I will double check when I get home late tonight. If somebody would like to correct or confirm this, please do!
