Gerry, I think that is the one I remember, judging from size. However, after I posted I did Google 'Scientific songs' and found a site called that, that does just them. Smaller, but very focussed, and soliciting augmentation.

Websites change so much, if you leave them for a while, you don't recognise them when you return.

I used to do 'Madeira, M'dear' m'self.
