Ringo sat around at Harrow central (5)
I believe the answer is:
starr
'ringo' is the definition.
(Ringo Starr of the Beatles)
'sat around at harrow central' is the wordplay.
'around' indicates anagramming the letters.
'at' means one lot of letters go next to another.
'central' says to take the centre.
The middle of 'harrow' is 'rr'.
'sat' is an anagram of 'sta'.
'sta'+'rr'='STARR'
(Other definitions for starr that I've seen before include "Ringo --, drummer" , "rush up north" , "English rock star and drummer, b. 1940" , "Ringo - (The Beatles)" , "Beatle Ringo" .)
