The Guardian, along with many papers, have Tony Warren's obituary today.
However, I'm linking to the obituary in The Guardian for a few different reasons. It's written well and has some interesting snippets of information in it. There's also some wonderful video clips to watch while reading.
Amongst the tributes, the obituary tells us that for several years during the 60s, Tony Warren's partner was Ernst Walder, who played Ivan Cheveski in Coronation Street.
