The Cream Pot is in Vickers - can't give a reference at the moment as I'm at work. However, I learnt it as Grace Hay's Delight from the Niel Gow collection and the Fiddlers Five CD. I noticed that people calling it the Cream Pot played a different B part so I looked it up in the Great Northern Tunebook and found an intriguing note - from memory, Vickers said something like "this second part is wrong, it is right on page ??" but the page referred to is missing from the manuscript - so perhaps he intended it to be the Grace Hay version? Now I'm outed as a real tune anorak!
