B1 "Parking Lot Blues" is by ESG, from their 1983 LP Come Away With ESP. The correct name of the Dinosaur L track on B2 is "#3 (In The Corn Belt)", it is from the 1981 LP 24->24 Music. I suspect Port Authority Blues is actually "Port Authority Bus Blues" by Port Authority from the 1971 LP The US Navy, but I have not heard the original record.
