Barman orders reconditioned grand to be wheeled in (7)
I believe the answer is:
rodgers
'barman' is the definition.
(composer Richard Rodgers - bars of music)
'orders reconditioned grand to be wheeled in' is the wordplay.
'reconditioned' indicates anagramming the letters (I've seen this in other clues).
'grand' becomes 'g' (G is short for grand as in a thousand).
'to be wheeled in' is an insertion indicator (some letters get brought in or wheeled in).
'orders' is an anagram of 'roders'.
'roders' going around 'g' is 'RODGERS'.
(Another definition for rodgers that I've seen is " He wrote musicals with Hart and Hammerstein".)
