'Flash', grand record by Queen (7)

Ross

I believe the answer is:

glister

'flash' is the definition.
(glister is a kind of flash)

'grand record by queen' is the wordplay.
'grand' becomes 'g' ('G' can be a synonym of 'grand').
'record' becomes 'list' (I've seen this before).
'by' means one lot of letters go next to another.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'g'+'list'+'er'='GLISTER'

(Another definition for glister that I've seen is " Gristle (anag)".)

I've seen this clue in The Telegraph.
