Be relevant to grizzly performing (4,2)

I believe the answer is:

bear on

'be relevant to' is the definition.
(I've seen this in another clue)

'grizzly performing' is the wordplay.
'grizzly' becomes 'bear' (I've seen this before).
'performing' becomes 'on' (as in being on stage).
'bear'+'on'='BEAR ON'

(Another definition for bear on that I've seen is " Be relevant to, concern".)

I've seen this clue in The Globe and Mail.
