So what is the earliest concert you can remember going to

The Buckinhams. Early 60's, think I was 5 y/o more or less; so long ago I can't remember exact age. LOL. At the Kenosha County fair. I did have an autograph......lol. Wonder if it would be worth something?
Dennis Tufano is still alive and touring with a modern version of the Buckinghams. Keep that autograph!
