You were the person who originally mentioned SJ here on the forum, weren't you? Good to see you getting involved again!

FWIW, I have that concentration thing too... and I never see it coming until the train has crashed. I can know a song note for note, but if my attention gets fixed on any other life detail, even for a moment, I can't pry it away quickly enough to keep the flow from breaking down.

But, what's a curse to the man on stage can be a blessing to the man in the studio, as a whimsical mind can lead to some pretty creative places. Unfortunately, once I've found those places, unless I write it down, I can't ever find my way back. ;-)

Break a leg!
