No, it's not Elsie Tanner on the right of this picture, it's the very wonderful Sue Johnston. The star of The Royle Family and Brookside played Pat Phoenix in the play The Things You Do For Love, along with Denise Black (Corrie's Denise Osbourne).
But Sue Johnston has another Corrie connection - in 1982 she made a guest appearance in Coronation Street as "Mrs Chadwick." She was the bookie's wife, and Fred Gee loaned Annie Walker's car to her in order to write off an £85 debt. When she left her gold lighter in the car, Annie assumed that Fred had got a high-class girlfriend!
Mrs Chadwick wasn't a permanent resident of the Street, however, as Sue very soon embarked on the role which made her name, that of working class goddess Sheila Grant in Brookside. She's been extremely busy ever since, with roles ranging from comedy (The Royle Family, Jam and Jerusalem) to deeply moving dramas such as Goodbye Cruel World. Big-screen roles have included Brassed Off.
