..bathroom on the right

Some of the words to this song of John Fogerty's seem to be prophetic to our times. Does anyone have a clue about the title? Is there actually a meaning behind it?

While looking up the lyrics I found out that a line in the song was not what I thought it was!

Don't go 'round tonight
For it's bound to take your life
There's a bad moon on the rise

The last line is "bad moon on the rise", but I always thought it was "bathroom on the right"!!
Duh!!!!

Trying to attribute the gift of prophesy to a man who mastered only 3 chords in his career is a leap.
