Mellotronists

I heard this song just today on a just-out compilation on the 
Bar/None Records label titled "The American Song-Poem Christmas" and 
given the fact that many of these songs have a children's 
1950's/1960's adult contemporary holiday theme about them, imagine my 
surprise when I heard what sounds like MkII strings and noodling like 
something off of Harrison's Wonderwall Music flailing about all 
through the song. I thought it might have been the Big Band Beat 
Optigan disc for a nanosecond, but the cool thing about this tune was 
that you can hear the key attacks loud and clear.

Upon doing a little research (the CD's liner notes tell nothing), I 
gfind out the song was the flip of a single from 1977. It sounded 
like 1962! I thought I was on to some ancient Chamberlin gem at least.

I wonder why the band was called the "Swinging Strings"? Someone 
trying to pull the wool over our eyes on a technicality?
