Artist had yarn with owl, taking part in Ramblings (4,6)
I believe the answer is:
andy warhol
'artist' is the definition.
(I've seen this before)
'had yarn with owl taking part in ramblings' is the wordplay.
I cannot really see how this works, but
'had' could be 'd' (in contractions e.g. 'I'd', 'you'd' etc) and 'd' is present in the answer.
'with' could be 'w' (short for with) and 'w' is found within the answer.
an anagram of 'yarn' is 'nyar' which is located in the left over letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for andy warhol that I've seen before include "US pop artist" , "Leader of the Pop Art movement, d. 1987" .)
