Hamish Hernderson wrote the following letter to Pete Seeger, from Edinburgh, dated 6 October 1961.

'Dear Pete,
I'm just back from a late holiday in Ireland and found a tower of letters - including your own, and one from a lad who listened to your rendering of the 'FreedomCome-All-Ye' at Carnegie Hall on 16th Sep. I'm most pleased to hear that you like the song and that you've already begun singing it.

Of the songs in Ding Dong Dollar, only two - the Freedom Come-All-Ye and the sequence called 'Anti-Polaris' - are by me. These you are quite at liberty to print in 'Sing Out'. For the others you should contact Morris Blythman, 109 Balgrayhill Road, Glasgow, who is 'inspirer and begetter' of the whole collection, and author (or part author) of most of tem.

Morris has already begun recording more material for a 12" LP, and the best thing would be for Moe Asch [Director of Folkways records] to get in touch with him directly at his Glasgow address.

Here is a glossary of my own song:

roch=rough. dawin=dawn.
heelster-gowdie=headover heels. gar=make. rottans=rats, vermin.
gallus=bold, reckless. loanins=tracks, lanes.
callants=young lads ('gallants' is a misprint).
crousely craw=arrogantly crow.
(like many Scots phrases, this is most difficult to render: crouse can mean a lot of things, including 'conceited' and 'arrogant'; in conjunction with 'craw', it has the overtone of 'harsh' and 'raucous' as well).
wee weans=kids. clachan=hamlet.
herriet=harried. ane til ither=one to another.
hoodies=crows. barley bree=whisky.
geans=cherry trees. dings doon=knocks down.

Looking forward to seeing you in Novemver, Youys aye, Hamish'

So there you have it, straight from the horse's mouth.

PS I think 'our own' Jim McLean was also involved in Ding Dong Dollar.
PPS There's a lovely, no-nonsense version of 'Freedom-Come-All-Ye', by trad Dundee singer Jim Reid, on 'Scotland;the Music and the Song; 20 year profile of Greentrax'[record label].
