'for vaulting now summer's here' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'go' is the wordplay.
I cannot really see how this works, but
'go' could be 'ring' (ringing is a kind of going) and 'ring' is found in the answer.
This explanation may well be incorrect...

'in' is the link.
