Customers at Ken Varey's Outdoor World did a double take back in 2011 when Bill Roache - who plays Street stalwart Ken Barlow - dropped in to open the new Skipton store. Bill is pictured with owner Kevin Horkin.

Shipley actor Bryan Moseley played Coronation Street grocer Alf Roberts for many years, and even became the Mayor of Weatherfield. Here Bryan is pictured with Sue Nicholls, who played his on-screen wife Audrey Roberts, at a photography exhibition called Alf’s Hat - inspired by Alf Roberts's trademark trilby - at Shipley’s Focus’d Gallery.

Back in 2010 Chris Gascoyne, who plays Peter Barlow, joined staff from the Black Bull, Haworth, in a charity walk organised by Mark Cartwright (front right), and in 2012 Bingley actor Peter Armitage, who played Kevin Webster’s dad, Bill, re-launched Skipton’s Swadford Centre after it was refurbished.

Jack P Shepherd of Pudsey went to Stage 84 in Idle and has been in Corrie since the age of 12, when he joined the cast as cheeky David Platt. Jack is pictured as a youngster showing his soap award to cast members of Grease at the Alhambra and, in 2004, at the Bradford’s Bravest Awards, 2004, with a football signed by the Corrie cast for the Bradford City Appeal. Jack is also pictured with the Mayor of Calderdale Nader Fekriis at a charity walk.

In 1972 two of the Street's biggest names, Bernard Youens and Jean Alexander - Stan and Hilda Ogden - opened Bradford's new Mother Hubbard’s fish and chip restaurant on Ingleby Road in 1972. Fans turned out to cheer as they toured the city in an open-topped Rolls Royce.

Finally, who can forget the famous Corrie courtroom scenes shot at Bradford's City Hall?

Back in 2007 Tracy Barlow’s dramatic murder trial was shot at City Hall's Victorian courtroom in 2007. Pictured are Anne Kirkbride (Deirdre Barlow) and Kate Ford (Tracy) rehearsing a scene. And in 2010 it was the turn of Gail McIntyre, as she was then (played by Helen Worth, pictured, centre), to be on trial, for murdering her husband, Joe. Two endings were filmed.

The City Hall bells played the Coronation Street theme tune while the cast were in town.
