He was. I used to love Phantom Of The Opera back in the day and had a copy of the original West End version with Sarah Brightman and Michael Crawford that I played all the time. It was 'lost' so I ended up buying the CD version of it. When he was cast in Corrie, I recognized the name but couldn't think from where until I was reading through the booklet a few weeks later and saw he played Firmin in the musical.Apparently he sounded quite posh in real life
Speaking of Corrie, I remember when it was revealed he was gonna be in it and a lot of people questioned why he would 'slum it' in a soap as he was seen as a 'proper' actor. Of course, it was a different story as soon as he was on screen.
Here is...I say, here is a video of his normal voice.
