Some kneel, visiting singer (5)
I believe the answer is:
elvis
'singer' is the definition.
(I've seen this before)
'some kneel visiting' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ELVIS' is hidden in the letters of 'kneel visiting'.
(Other definitions for elvis that I've seen before include "Mr Presley" , "The King, d. 1977" , "Jailhouse Rock star" , "Musically, The King" , "The familiar R 'n'Roll king" .)
