Those are the Alstrom cars that replaced the Budd "Almond Joy" cars of 1960 that replaced the Brill center entrance cars of 1907, 1914 and 1922.

The song dates from 1970. I got this group to perform at a dance at Drexel in that year, but I was not impressed with their act.

Wow, were those 1907 cars pulled by horses?       :-)      (That was a wee bit before my time!) If memory serves me, I once saw the American Dream at the "Electric Factory" (a very long time ago).   I only remember two songs they did -- the Frankford El song, and one called "Raspberries".   I liked the Frankford El song because it sounded like a good old country song.   (One of the rock & roll radio DJ's back then used to refer to someone as "the hillbilly from South Philly", but I don't remember if he was referring to one of them or to someone else.   Do you remember that?)
