Sailor's Tale live at the Zoom Club is rough as well. Beautifully out of tune MK-II Brass near the end!
I have about 70 live recordings of KC in various guises, and of all of them I'd say the Tron was in tune in maybe four or five. The rest of them range from 'a bit iffy' to 'miles out'.
Worst was the Cross/Wetton/Bruford/Fripp effort, where they played two Trons and a violin against each other sometimes. Fortunately they improvised around little tonal centrality, which helped. Wetton playing at earthquake levels was probably an effort to disguise it all as well.
