Heard aboard loose ships making slogan for mime (3-4)

Ross

I believe the answer is:

lip-sync

'mime' is the definition.
(to lip-sync is to mime along to a song)

I can't explain the rest of the clue.

(Other definitions for lip-sync that I've seen before include "Linking of speaker's mouth movements and voice in filmed recordings" , "Align mouth movements with recorded speech" , "Audio and video alignment of speech" .)
