I remember this too. David L Burgh as I recall who looked a bit nerdy so they substituted him with this rocker! To my mind, he looks like he's celebrating an epic fart. Any who... you can't learn perfect pitch. Well, correction, you may have it and develop it but for most people, you don't have it and can't get it. Don't worry - pretty sure none of the Beatles had it and they won music. Also, people who do have it, can lose it in middle age. It can also be torture for people who have it as instruments aren't perfectly in tune. Relative pitch we can all develop and that is a very pragmatic skill.
