The Pipes of War blog tells his D-Day story and there is an extended account from him, which is "the primary source."

That is a minor point to some, perhaps, but details are important.
Piper Bill Millin Memorial is to be unveiled on the commemoration of D-Day in 2013.
Here is a YouTube video about his life.
