THEY pioneered the Rockney genre with their blend of Cockney slang, music-hall humour, and rock'n'roll - and 40 years on, inseparable duo Chas & Dave are still going strong.

Following on from the release of their first studio album in 27 years, they are back on the road with a new madcap tour showcasing their own material and a choice selection of their all-time idols’ legendary songs.

After sinking their teeth in the industry playing for a string of different bands, the pair decided to join forces in 1975 and create a new sound that was uniquely British and rockin' to boot. They went on to release a string of chart-toppers including Gertcha, Rabbit, The Sideboard Song, and Aint No Pleasing You. They have travelled the world and crossed length and breadth of the country ever since, delighting audiences with their down-to-earth charm and tongue-in-cheek ditties.

Chas & Dave’s appeal has never been greater or more varied. Their audience is getting younger without the boys deliberately trying to appeal to the youth, and bands like The Libertines are citing them as a major influence.

After high-profile gigs at Glastonbury in 2005 and 2007 and Bestival in 2012, their contribution to popular culture was compounded with a BBC Four documentary retracing their career. It featured a roster of industry fans including Jools Holland, Phill Jupitus, and Pete Doherty. On the back of the programme they were invited to close the 2013 Royal Variety Performance and were joined by Gary Barlow, Robbie Williams, Mary J Blige, and Jessie J among many others in a roof-raising rendition of London Girls.

The same year, Chas & Dave performed a sold-out show at the Royal Albert Hall. They were also recognized by the Nordoff Robbins Foundation who awarded them the 2014 Silver Clef Icon award at a ceremony that included fellow award-winners Pharrell Williams, Paloma Faith, Sir Tom Jones, and Giorgio Moroder.

Their first studio album in 27 years, the critically acclaimed That’s What Happens, saw Chas & Dave return to their roots in 2013 - with a collection of early R&B, skiffle and rock n’ roll classics alongside new takes on their own songs. It featured collaborations with Albert Lee, Martin Taylor, Buddy Holly and The Crickets’ drummer J. I Allison, Jools Holland and Hugh Laurie.

They recently performed at the BBC/Royal British Legion Party to Remember concert at Royal Horseguards alongside Status Quo, Gregory Porter and Catherine Jenkins.

Chas & Dave appear at the Wyvern on Sunday at 7.30pm. Tickets start at £30. To book visit swindontheatres.co.uk or call 01793 524481.
