Performing vocals, drinking whisky and being indecisive (8)

Ross

I believe the answer is:

swinging

I'm a little stuck... Click here to teach me more about this clue!

'being indecisive' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?

'performing vocals drinking whisky' is the wordplay.
I cannot really understand how this works, but
'whisky' could be 'w' (phonetic alphabet: alpha, bravo, charlie etc.) and 'w' is located in the answer.
'performing' could be 'singing' and 'singing' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...

'and' is the link.

Can you help me to learn more?
