I add my name to the dedicated rather than hardcore fan. I have all their official cds a few vinyl Australian album releases (tracks the same covers different) some posters and t-shirts, etc. Only have a couple of solo albums.
During my teens I was as obsessed as a person with limited pocket money could be (mairi, totally know where you're coming from) and relied heavily on taping the songs from the radio and borrowing any book I could about them from the library.
But Beatles no longer dominate today, I like some current stufff as well as older stuff and my listening time is sadly working through the Harry Potter audio cds!!! (sad, I know)
