Hotel pages Spooner's underworld dances (8)

I believe the answer is:

bellhops

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

'hotel pages' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe you can see a link between them that I don't see?

'spooner's underworld dances' is the wordplay.
'spooner's underworld' becomes 'bell' (I can't explain this - if you can you should give a lot more credence to this answer).
'dances' becomes 'hops' (hop is a kind of dance).
'bell'+'hops'='BELLHOPS'

Can you help me to learn more?

(Another definition for bellhops that I've seen is " Hotel porters, pages".)

I've seen this clue in the Sydney Morning Herald.
