The Holy Modal Rounders also did a version of "Red Rocking Chair" on their album "Alleged in Their Own Time", in which "Sugar Baby" became "Honey Baby". I can thoroughly recommend this and also their double album on Rounder Records which I think is simply called "The Holy Modal Rounders". The latter is of socio-historic interest as it used phrases such as "strutt their stuff" and "I can't abide no woman who goes round sniffin' glue", which shows that these phrases were not just products of the 1970s/1980s. Mind you the word punk is apparently a very old English word for a woman of easy virtue. Not so fussed about the more psychedelic and self-indulgent stuff the HMRs did, although there are 2 or 3 nice songs on "Last Round", etc.
The Crawdad Song is also on a CD by Doc Watson - the tune seems to be similar to the one used by Bob Dylan for "Frog Went a Courtin", the last song on his CD "Good as I been to you", a mostly acoustic folk/blues album. The album if rather uneven; personally I think his version of Stephen Foster's Hard Times poor, but "Canadee-i-o" is an excellent song which I hadn't heard before. Despite being twee and familiar I actually think Frog Went A Courtin actually the best song on the CD, though sadly probably not suitable for children because of the violent ending, ie the Frog, Mouse and Rat all get eaten!
