Consequences about drums on Sunday (13)

I believe the answer is:

repercussions

'consequences' is the definition.
(I know this)

'about drums on sunday' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'drums' becomes 'percussion'.
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'sunday' becomes 's'.
're'+'percussion'+'s'='REPERCUSSIONS'

I've seen this clue in The Daily Express.
