Back in the day, I went to plenty of concerts (some I remember better than others) Doors, Jefferson Airplane, James Gang, John Sebastian, Three Dog Night, Blood Sweat and Tears, Weather Report, The Crusaders, the Dead, 4 Tops, Temptations, Crosby Stills and Nash, David Bromberg, etc
Saw Marshall Tucker Band at Red Rocks and sat next to a girl from Germany who was probably 15. She kept elbowing me in the ribs and screaming "First American Rock Concert" while her boyfriend barfed all over everyone in the area.
Between work and kids I don't get out much these days. Probably the last concert I went to was to take the kids to the Manheim Steamroller Christmas concert.
