Steve first moved to the cobbles in 1989 with mum Liz (Beverley Callard), dad Jim (Charles Lawson) and twin brother Andy (Nicholas Cochrane).
Steve and Andy are twins but non-identical so actors Gregson and Cochrane are not related in real life.
They were also very different as characters with Steve continuously being up to no good, gambling and getting sent to prison, Andy was the brainbox of the family.
But in 1993, Andy made the shocking decision to drop out of Sheffield University to marry girlfriend Amy Nelson (Louise Deprey).
