A song titled Crushed by the Wheels of Industry seems an incongruous party anthem for revellers in the sunshine at Let's Rock Earlham Park.

Similarly Heaven 17's opener Fascist Groove Thang speaks of a time when the Sheffield outfit were high-minded electronic pioneers with a political mission.

Here the mission was purely to entertain, and boy did they deliver.

That they followed it up with a redition of Happy Birthday for keyboardist Berenice Scott suggested they were in a party mood.

Original members Glenn Gregory and Martin Ware, who formed the band out of the ashes of the original Human League, were clearly having as much fun as the rest of us judging from their beaming smiles.

Heaven 17's debut, Penthouse And Pavement, is, and remains, a classic. Follow-up, The Luxury Gap, was their pop masterpiece.

The set included their lovely electro-soul ballad Come Live With Me and a guaranteed crowd pleasing cover of Bowie's Let's Dance.

But aided by some incredible soaring vocals from backing singers Kelly Barnes and Billie Godfrey, it was monster hit Temptation, as ever, that proved an irresistible finale.
