Who is Sylvia? (Patreon)

Here's a relic from 2001.  Words (not heard in this version) by William Shakespeare.  Music composed by Franz Schubert, performed by me on piano and mandolin.  The mandolin is playing the vocal melody.  There was a version of this in which I sang, but it was extremely embarrassing and it looks like I didn't save it.  Which is undoubtedly for the best.
