Perhaps Prince covers No. 1 from Peter Gabriel - ultimately having a try in various keys? (11)
I believe the answer is:
archipelago
'perhaps prince covers no 1 from peter gabriel ultimately' is the definition.
I can't judge whether this defines the answer.
'a try in various keys?' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'try' could be 'go' (both can mean an attempt) and 'go' is found within the answer.
'in' could be 'hip' (both can mean fashionable) and 'hip' is found within the answer.
This explanation may well be incorrect...
'having' acts as a link.
Can you help me to learn more?
(Other definitions for archipelago that I've seen before include "Philippines, say" , "Fiji, perhaps" , "Large group of islands" , "Extensive group of islands" , "the Aegean, originally" .)
