The Chris and Peter Allen LP was issued in the US and no doubt can still be had quite cheaply.
Appreciate the review of the Roy Rutanen LP. One of the tracks turned up on my Facebook feed, must have been "The Trip Song," which certainly bode well for the LP as a whole. But, alas, things are not always what they seem. Still, quite the scarce LP apparently and one which has thus far evaded reissue, to my best knowledge.
