Just a clarification, Sanders. The David and Brian I was referring to in the last post were not THIS David and Brian.

These two ARE NOT getting married by the Reverend Ruby Montana poolside at the Coral Sands. No . . . no.

This David and Brian are merely releasing a new album. It's called "Everything That Happens Will Happen Today". To smooth over any rough feathers this reporter may have caused, were offering Sanders a free download of a song off the new album.

Hope this clears things up.
