Hi Scott
You just about got it in one........ Way back in the 1950s I saw a US Forces Rifle Drill Team, perform marching & intricate rifle drill (with bayonets fixed) to that rendition of St Louis Blues. It has stuck in my mind all these years and I hope I've reproduced something close to what I heard then.
As for the sleepwalk sounds - an e-mail is already winging its way across the big pond.
I've already mailed Bill Norrie my thanks for the conversion to mp3, but publically thanks again Bill.
