Odd sailor gets up to dance (5)
I believe the answer is:
rumba
'dance' is the definition.
(rumba is a kind of dance)
'odd sailor gets up' is the wordplay.
'odd' becomes 'rum' (I've seen this before).
'sailor' becomes 'ab' (abbreviation for able seaman).
'gets up' says the letters should be written in reverse.
'ab' backwards is 'ba'.
'rum'+'ba'='RUMBA'
'to' acts as a link.
(Other definitions for rumba that I've seen before include "Cuban folk-dance" , "Burma (anag)" , "music one can dance to" , "Afro-Cuban or ballroom dance" , "Latin American dance" .)
