Same here. Back then I would have thought it was a 'tea caddy'.
Or someone who carries your golf clubs?
Playing my vinyl copy now (Blue Note 4230). Is this one of the Mobleys where the tracks are re-arranged on the CD? I have "A Caddy for Daddy", "The Morning After", "Venus Di Mildew", "Ace Deuce Trey" and "3rd Time Around".
That is the track order also on my BN NY USA stereo copy of the LP.
My 1990 CD copy has the same track order too.
