I’m going with Ted Nugent or Johnny Cash.
I’ve loved The Beatles the longest but I have seen McCartney three times and Ringo twice.
Pink Floyd; I saw twice (without Waters) Gilmour once and Waters once
Maybe Led Zeppelin but I’ve seen Jimmy Page twice.
But as an early teenager, a friend of mine had Double Live Gonzo, Scream Dream, and Weekend Warrior that we listened to often when his mom was at work. Double Live Gonzo especially was just such an ear opening experience every time we listened.
I hesitate to mention Johnny Cash because maybe I’m more of a casual fan. My dad played Johnny Cash albums and 8-tracks often so I have an admiration for his music and there are about thirty of his songs I will sing along to. However I have never bought any of his studio albums. I have a few of my dad’s records and a few compilation albums but for me the definition of a true fan is someone who has bought and enjoyed and also cherishes studio albums
