QotD: My First Single

Music-wise, what was the first 45, single or download you bought? 
Submitted by Paddy Melt Wagon.

Gosh, it was a really, really long time ago, but I am just about 100% sure that the first 45 I ever bought was The Beach Boys' "Good Vibrations."  And I'm equally sure that I played it over and over and over again, while my mother cringed and/or yelled, "Turn that music down!"  Luckily, I still really dig that tune, so I can disclose my first 45 purchase with pride! 

One summer when I was about 11 or 12, I went to see the Beach Boys at the Indiana State Fair with my brother and his Mormon girlfriend, Pam.  Pam was my brother's first official "girlfriend" and I think he was trying to show her his family-loving, sensitive side by inviting me to come along with them.  It was thrilling for me to see the Beach Boys but also very odd for me to be out on a date with my brother and his girlfriend.  At some point during the show, I saw him lean in close to her and say, "This would be a lot better if my sister wasn't here."  Oh!  Ouch!  My poor, fragile pre-pubescent self esteem!
