Hi Passion, I don't really hold with a concept of 'the correct key'.
I used to work a lot with singers; one key would suit one singer's
voice better than another etc. so you learned to be flexible. I also
find it difficult to believe Coltrane played that tune in C#m/E.
Cm/Eb is much better suited to a Bb instrument. Perhaps there is a
problem with the speed on the recording.

Of course there are keys which are commonly used for standards but
they're not carved in stone. I heard a story about a guy who sat in
with Herbie Hancock; Herbie called a tune in Eb and the guy said,
hey, that's in F isn't it? Herbie just smiled and said ok...

Regards, Liam
