Congratulations. :) I remember a few years ago having so much fun tracking down all the albums to complete my collection...I'd try Amazon for the solo ones, I think I got all of Roger's used on there and they come in great condition.
I still haven't managed to track down The Cross' albums...I'm a horrible Queen fan!
And I agree about that feeling of listening to Made In Heaven...it's just so surreal listening to Mother Love and thinking that this is the last of Freddie's voice.
Resistance is futile. You are now an orb.
