Musicians allegedly "up above” in crazy starship (8)

I believe the answer is:

harpists

'musicians allegedly up above' is the definition.
(angels are often depicted playing harps)

'crazy starship' is the wordplay.
'crazy' is an anagram indicator.
'starship' is an anagram of 'HARPISTS'.

'in' acts as a link.

I've seen this clue in The Times.
