Concerts these days are way out of my budget. I had my fill in the 60's and 70's. Young & dumb, me and my buddies packed into Woodstock, quite an experience. Since then I've seen Skynyrd, Neil Young, The Stones & a few I've forgotten. Also enjoyed seeing a few before fame, Linda Ronstadt & the Stone Pony's in a small cowboy bar in AZ and R.E.O. Speedwagon in a college bar in Champaign/Urbana. Never had the urge to join screaming 12 year old's to see the Beatles.
My first concert was The Beach Boys at a colosseum with wooden fold up chairs in the main section. Some of the crowd was upset when they discovered Brian Wilson was ill and had been replaced with a sub and started throwing chairs at the stage. The sub was Glenn Campball and he hit every note perfect.
