Aside from that -- the most notable thing about Mangione to me -- was serious endurance.
I mean this dude was playing songs for like 12 -15 minutes at a time without a break -- (and it all sounded great) --- low to high, slow and fast -- and I thought "AWESOME - wish my lips could hold out for 15 minutes at a time -- and do that for a 3 hours show
ps. I have the LP's (vinyl record of "Feels So Good") and a record player -- and there is something very nostalgic about that!!!- but I am old too
