I can find next to no information about The Wayside Trio online. They only released one album, as far as I can see, and that was apparently a result of their winning a contest at the 1964 California State Fair Exposition. (The album was, appropriately, titled "Winners: The California State Exposition.")
If I had unlimited time and resources for this blog, I'd visit the California State Archives and see if I could find a picture or poster or something in the Fair's extensive files. Alas, I do not.
Anyway, this is a friendly, upbeat acoustic folk take on Stag, with a nice opening whistle. I tend not to like this early 60's well-scrubbed, inoffensive "folk" style, but this is peppy and I don't mind it at all.
