I too would like to piggyback on the sentiments from my predecessors...Threshold and Mac acquired a fan for life the night they played at PPUSA III. Their performance that night has a permanent place in my Top 10 best sets at ProgPower. Mac could sing the phone book and I would buy it...what a sad day indeed. I too heard the rumors about him joining Galloglass (a great band in their own right), and even hopped on board the Mac train with Yargos and PowerWorld.
You will be missed, my friend...RIP.
