I saw the movie, "Poor Cow" many years ago. Donovan sings, "Be Not Too Hard" in the movie soundtrack but as I recall the song is interupted when the actors start talking again. Does anyone know if there is another version of Donovan singing this song (other then in the movie), "Poor Cow?"

I tried doing a search but could not find where Donovan sings this song on any other release. Perhaps a bootleg?
I would like to be able to hear the song without the talking.
Of course I do have the Joan Baez version but looking for Donovan singing it alone (not in aoundtrack). Thank you.
