With the help of one of my techie friends, I made a filk album some years ago (under my fanish name).
This included original words and music and filks of other people's songs/music- ranging from Chris 'Minstrel' Malm to Franz Schubert.
[At that time I had a singing teacher who used to work with the English National Opera and she showed remarkable patience. I would be leaning some Mozart, or Gilbert & Sullivan and would keep coming back the next week with a new set of words...]
Once I had decided to do a tape, I had to think about the concept and the tape cover.
I recently found one of the mock-ups I drew.
