Chap creating celebrities broadcast (8)

I believe the answer is:

alistair

'chap' is the definition.

'celebrities broadcast' is the wordplay.
'celebrities' becomes 'alist' (A-list).
'broadcast' becomes 'air' (to air on TV).
'alist'+'air'='ALISTAIR'

'creating' acts as a link.

(Other definitions for alistair that I've seen before include "-- Maclean, author" , "Man" .)

I've seen this clue in The Irish Times.
