[Dixielandjazz] LP Recording - Here's one to ponder

[M J (Mike) Logsdon]

>>>Did he do it the same way Monty Python's Flying Circus did it?  One 
of their LPs had two different tracks side by side on one side of the 
record.  Whichever of the tracks the needle fell into out of the 
landing zone was the one you heard.<<<

That would be the "Matching Tie and Handkerchief" album.  They issued two versions, one with the side with two parallel grooves, and one standard with no gimmicks.  I own the standard one.
