You could add the "#" like this (in the file "out.ly"):

music  = \relative c' { c4 d e f g a b c d e f g a b c }

{
  #(with-output-to-file "display.txt"
      (lambda () (display "#")
                  #{ \displayMusic \music #}))
}

Now, as for doing everything within a single file, I'm at a loss.
Hopefully, somebody could help here.
