I've just pulled my copy of
Actual Miles off the rack and it differs from your copy RudieCantFail. There is no mention of a 13th track on the disc or in the CD booklet. My copy only has the lyrics to
The Garden Of Allah included.
There's a red sticker on the case:
The special bonus track;
Everybody Knows, remains anonymous.
I think
Everybody Knows had been released a year or two earlier on a Leonard Cohen tribute album, which may explain the secrecy.
Don sang
Everybody Knows with Bryan Adams on some global televised benefit show, which were common at the time.

Don also sang Cohen's
Democracy , live on MTV at Bill Clinton's Inaugural Ball in January, 1993, along with
Dirty Laundry, The Heart Of The Matter and Dylan's,
The Times They Are A Changing. https://www.youtube.com/watch?v=USlHqwTQVrU
Don was very contemporary in the early nineties. Twenty years in the "second act," of the Eagles turned him into a relic from the 1970s.
