The official musical,Street of Dreams, featuring Kym Marsh and Corrie veterans Julie Goodyear and Kevin Kennedy, was performed just twice in 2012 before it was shelved.
Asked whether he was a fan of Coronation Street, comic Paul told the Radio Times: “I was, and then they did an awful musical and that put me off for the year.
“I couldn’t even listen to the theme tune, but about six months ago I started getting back into it.”
Paul recently played a cancer patient in Holby City.
He said: “I turn down a lot of scripts. If they’re looking for a nightclub owner, or someone peddling hookers, I’ll get the script. Some of them are offensive. But with Holby I jumped at the chance because it was so different.”
He said of his TV viewing: “I’m not keen on these Man with the Ten-Stone Testicles programmes – they’ve become a Victorian freak show. I’d also whittle down the cookery because everyone on TV has a whisk in their hand.”
Paul said Lady Gaga, who has twice been a guest on The Paul O’Grady Show, is his friend, but added: “If there’s somebody I’m not mad on, I go in with my arms folded saying I can’t bear them and I don’t shut up until they relent.”
