Career: Walsh's big TV break came in 1993, when he appeared on the Royal Variety Show. It led to a stint presenting the National Lottery, and he also hosted the game shows Wheel of Fortune and Win, Lose or Draw. After fearing his brand of light entertainment was becoming dated he moved into acting, taking parts in the TV version of Lock, Stock, the soap Night and Day and movie Mike Bassett: England Manager before Coronation Street's bosses created the role of Danny Baldwin for him in 2004. He stayed in Weatherfield for two years before leaving to pursue other projects. He's since appeared in Torn, The Old Curiosity Shop, The Sarah Jane Adventures, Law and Order: UK and SunTrap. He moved back into presenting in 2009 with ITV quiz show The Chase, and is a team captain on Play to the Whistle.

Career: Audenshaw joined the long-running soap in 2000 as Bob Hope, a love interest of Viv Windsor. Bob proposed to Viv while drunk and they married in 2001. They divorced four years later after Viv had an affair with Paddy Kirk but they reconciled and married for a second time in 2006. Bob had his hands full when Viv gave birth to twins and was left holding the babies when she was sentenced to three years in prison for fraud. He tried to run the café and post office as well as work shifts in the Woolpack and raise the twins on his own. He was shocked when Viv was suddenly released from prison, but they eventually come to the realisation that they were no longer compatible. The current love of Bob's life is Brenda Walker.
