On Kevin Dubrow webpage you could listen to and download an unreleased track featuring Randy Rhoads.

"This song titled "Come And Gone" was recorded live in the studio in early 1975. It has never been released and by listening you can tell that even then at 17 years old Randy Rhoads had great potential. We had a manager that had accsess to free studio time so we regularly went in and recorded. Randy was so much fun to work with, was very serious about music and very serious about having fun. Enjoy!!"
