Yes I do all my own vocals.
Since you asked. Here is my original version of "Desire" with me playing and singing all parts:

And here's the band version:
Wow, what a gorgeous song. I've heard a number of your songs posted on TB, this is definitely a favorite. Such great chord changes, and the way you easily negotiate them made me think of Sandy Denny, which is highest praise from this quarter.
As the versions, and to mention Sandy Denny again, I prefer her solo piano versions to some of the orchestrations on the Fairport Convention LPs. But there is room for both. Hot jazbo playing on the redux, for sure... Although the break is a digression from your song, a distraction, arguably, rather than an amplification of the song's energy. But then it like a jazz band soloing around standards, isn't it. They jump off from there and often go on long digressions....
Anyway, all the money IMHO is in the demo version, your voice is just so gorge, and that the parts where you sing about your burning desire were sexy. You really convey the feeling of deep enchantment with someone. And the complex melody implies complex love. Doesn't need fairlight strings.
On the credit question, I think savvy advice would have been to part out the rights so that you retained the original while giving them usage for their "jazz version." Since you granted permission, you weren't robbed, but it sounds like you were manipulated/guilted into.
Worth getting the rights back... Or just assert the right by putting your version out there. If they complain spit fire.
Again, beautiful song!
