The Merry Xmas Everybody singer quit the group in the 1990s to go solo, and he has endured a frosty relationship with his former bandmates ever since.
Noddy reveals they tried to put their differences aside at a meeting five years ago, but the gathering ended in disaster.
"It really saddens me that the four guys who were in Slade can't get together now and sit round the dinner table," he tells Britain's Event magazine. "Five years ago I got the four of us together so we could air our grievances face to face, but it was so painful I'd never want to repeat it. I was shocked."
