Singer Benatar (3)
I believe the answer is:
pat
'singer benatar' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pat that I've seen before include "'Light touch, on the back say (3)'" , "Glib; touch affectionately" , "Apt for tender touch" , "Hit lightly" , "Girl" .)
