Beau's dad (5)
I believe the answer is:
lloyd
'beau's dad' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lloyd that I've seen before include "Marie -, nineteenth to twentieth century English music-hall entertainer" , "Bridges perhaps" , "Frank -- Wright, US architect" , "Christopher - - , garden expert" , "Harold - - , silent comic" .)
