Local band recordings wanted to air

Sarah Harvey….I am looking for recordings of local bands who played in the 1970s although they need to be the actual recordings from the 1970s. This is in connection with a programme I am looking to air on my internet radio station so I am hoping you will allow me to play them on it. As you can imagine, these are really difficult to come by and whilst I have some, I don’t have nearly enough. I don’t mind if they are on tape or digital or even vinyl… I will find a way of using them. And although my memories are mainly from the 70s, I don’t mind dipping into the 60s or 80s.
