When they perform a gumboots dance, it is minus the boots - these gents are all kitted out in sober grey suits and crisp white shirts.

A couple of the schmaltzier numbers take them right into Boyz II Men territory, complete with beseeching hand gestures, superfluous vocal ornamentation, "inspirational" spoken word interludes, the mandatory key change and the fixed smiles and catalogue poses into which the band freeze-frame after each song.

But these lapses into sentimentality are contrasted with physical humour and South African song-and-dance numbers brimful of vitality.

In any case, their four-part singing is simply exquisite. Some context regarding their repertoire would have been nice though. If their English language songs are any barometer, Africa Entsha are big on heart-swelling messages of solidarity and spirituality.

What could have been a soppy number dedicated to "all the mothers" acquires greater poignancy coming from a country which has been ravaged by Aids. A song "for the pretty ladies" is as cheesy as its introduction might suggest but the relish with which the bass singer delivers the line "oh yeah baby" is something to behold.

All delivered with utter sincerity, a warm depth of tone and a whole lot of soul.
