Who was that busking band that resembled the Specials?
They did resemble the Specials, with their wardrobe and style of music, no?
The band are "D Lime - featuring Tobago Crusoe".

It's probably more accurate to say that The Specials resemble them, seeing as the Specials and other 2 Tone bands were part of a ska revival and therefore heavily influenced by the earlier ska bands of the late 50s and early 60s.
