Dance and drink to sailor's return (5)
I believe the answer is:
rumba
'dance' is the definition.
(rumba is a kind of dance)
'drink to sailor's return' is the wordplay.
'drink' becomes 'rum' (rum is a kind of drink).
'to sailor' becomes 'ab' (abbreviation for able seaman).
'return' shows that the letters should be reversed in order.
'ab' in reverse letter order is 'ba'.
'rum'+'ba'='RUMBA'
'and' is the link.
(Other definitions for rumba that I've seen before include "Cuban folk-dance" , "One from Cuba" , "one's on the floor for it" , "music one can dance to" , "Cuban folk dance" .)
