Line dance? (5)

I believe the answer is:

conga

This clue is a double definition.

'line' is the first definition.
(conga line is a kind of line)

'dance?' is the second definition.
(conga is a type of dance)

(Other definitions for conga that I've seen before include "Latin American dance with three steps and a kick" , "wiggling line" , "Latin-American dance" , "Party dance" , "Long-line dance" .)

I've seen this clue in The Telegraph, The Times, The Guardian and the Sydney Morning Herald.
