March perhaps failing to start, say - none getting active (2,3,2)


I believe the answer is:

'active' is the definition.

'march perhaps failing to start say none' is the wordplay.
'march perhaps' becomes 'month' (march is a kind of month).
'failing to start' means to remove the first letter.
'say' becomes 'eg'.
'none' becomes 'o'.
'month' with its initial letter taken off is 'onth'.
'onth'+'eg'+'o'='ON THE GO'

'getting' acts as a link.

(Other definitions for on the go that I've seen before include "Keeping busy, not stopping", "Very active (colloq.)", "Very busy, in constant motion", "Active, in constant motion", "Active and energetic".)

I've seen this clue in The Independent.
