Louis Armstrong provided stray cats with some new homes (7)
I believe the answer is:
satchmo
'louis armstrong' is the definition.
(I've seen this before)
'stray cats with some new homes' is the wordplay.
I cannot really see how this works, but
an anagram of 'cats' is 'satc' which is within the answer.
This explanation may well be incorrect...
'provided' acts as a link.
Can you help me to learn more?
(Other definitions for satchmo that I've seen before include "Louis Armstrong's byname" , "Louis Armstrong's nickname" , "Name used by jazz player Louis Armstrong" , "Jazz musician" , "trumpeter" .)
