Jim, it's funny you should post this right now.
I just put up a post about how I recently bought a McIntosh MC 275 in large part, as a tribute to my father.
http://www.audionervosa.com/index.php?topic=7062.0There was no doubt in my mind what the first piece of music to be played on this amp was going to be. My parents were big Harry Belafonte fans (as a matter of fact one of their first dates was an outing to Prospect Park in Brooklyn, to see a Belafonte concert.) As such the Belafonte a Carnegie Hall was a musical fixture in our home when I was growing up. And as preschoolers, my sister and I always used to beg him to play Mama Look a Boo Boo. I guess at that age we liked the silliness of the song and the fact that it was a story about kids busting on their father. Since this amp was a tribute to him it seemed the only appropriate way to kick things off.
Besides that, the other song that would come to mind is The Beatles I Want to Hold Your hand. Meet the Beatles was the first record that I ever owned personally. While there were many records in the house, I got Meet the Beatles as a Christmas gift and it was the first one that was MINE. It was also the first one that I was allowed to put on the "record player" by myself. back then we of course had an automatic changer so I would put it on the spindle, hit start and the player would swing the arm over and drop the needle for me and I Want to Hold Your Hand was this first song on the album, so it was always the one that started of the listening session for me.
That record is beat to hell, but it is still has a place of honor in my record rack. I guess it is just hard to part with your first love.
