Hal-an-Tow is also on an LP (don't know the name) by Porterhouse c 1968 (from Neath, where I live).

I do have an old tape copy somewhere of Giles Farnaby's Dream Band (made in the UAE, where piracy was legal). The tune is similar in parts to the one used for Wheatley Processional

'This is it, and that is it, and this is Morris Dance sir,
The piper fell and he broke his neck, and he said it was a chancer'
on Morris On (or was it Son of Morris on?)
