Ushers with little drink remedy, then sailor marries (5,2,3,5)

'ushers' is the definition.
I know nothing about this answer so I can't tell whether this works.

'little drink remedy then sailor marries' is the wordplay.
I cannot really understand how this works, but
'little' could be 'l' (abbreviation for little) and 'l' is located in the answer.
'drink' could be 'the' (I have seen 'French drink' mean 'the' so perhaps 'drink' could also mean 'the') and 'the' is found within the answer.
'sailor' could be 'tar' (slang term for a sailor) and 'tar' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

'with' acts as a link.

Can you help me to learn more?
