My taste in music tends to be a little different than many guys, but like Tony from Tulsa in the TV thread, I'll out myself a bit (no not that way). The first concert I went to was Alabama and Juice Newton. I went alone and sat as far away as there were seats. How sad!
As for others, I have seen Air Supply and Whitney Houston, Barbara Mandrell, Kenny Rogers (twice), Lee Greenwood, Michael Bolton, Oak Ridge Boys, and some others. Lee Greenwood, during the pinnacle of his God Bless the USA days, was doing something in the same arena when my wife was graduating from high school (before I knew her). It is said that he asked what was going on. Someone told him there was a big high school graduation. Lee arranged, on the fly, to interrupt the graduation and sang God Bless the USA. I think it was an a capella version of the song. Can you imagine?
Now you're wondering when the "outing" begins, and that comes here: I am a fanilow. I've seen Barry Manilow twice in concert, simply because I love his unique voice. He was huge in the 70s and early 80s (though you would not know it on the "oldies" stations today). I have to say his was the best concert, followed by Kenny (back in the day), with lots of focus on the music and not just the lead vocals. Recently, he has focused on some cover albums, but is expected to release a guitar-driven rock album sometime soon (I know - that sounds weird to me too.). Besides, there were lots of girls at the concerts who couldn't get their boyfriends to bring them.
Now I'll go tune up the tractor and move some hay before I go on my big game hunting trip. (Is that what I'm supposed to say to replenish my testosterone, Tony?)
