Apologies for the slight thread drift, but Greentrax have just published the latest in The Scottish Tradition series. It's dedicated to the work of Calum MacLean. Here's the discogrpahical data.

Scottish Tradition 26. Cruinneachadh Chaluim; Field Recordings of Gaelic Music and Song From The Highlands and Islands by Calum MacLean. Greentrax CDTRAX9026D. Double CD.

There's no waulking songs unfortunately, but tons of everything else.

I've heard a discussion recently about waulking with the feet. It's not on the Scottish Tradition, unless I'm having the mother of all senior moments, so i think it must have been on one of the two CDs which Mike Yates assembled; Hamish Henderson Collects-Songs, Ballads & A Story From the School of Scottish Studies Archives. Kyloe 107 & 110.
