In Iowa, mid-50s: SHOT-ish. (And it was ALWAYS the same tune, the one I've seen in books called "Rustic Dance.")
From Norman Kennedy, Scots singer and weaver: sho-TEESH. Note that he has the "shot" beginning, not the "scot" syllable that Murray had, but did have the accent on the last syllable.
Hope this helps.
... But I doubt it.
