Work of famous compiler: ten down "Chinless bastard" (4,2,3,6)

I believe the answer is:

send in the clowns

'work of famous compiler' is the definition.
(Stephen Sondheim song - he also wrote crosswords)

'ten down chinless bastard' is the wordplay.
'bastard' indicates anagramming the letters (bastard can mean impure or mixed).
'ten'+'down'+'chinless'='tendownchinless'
'tendownchinless' is an anagram of 'SEND IN THE CLOWNS'.

(Another definition for send in the clowns that I've seen is " Sad song".)

I've seen this clue in The Independent.
