I remember one of those radio recordings was Pollyanna Live At The Wireless from Triple J and on the other side of the tape was Ammonia's Live At The Wireless. I would take that tape with me everywhere I went and play it with pride.
I played that dodgy old cassette within an inch of it's life, and then... til it's death. I wish I still had that recording as I had some very good times listening to it. But I'll always have the memories, oh and YouTube I guess.
