Tom Glazer's "On Top of Spaghetti," a rewrite of "On Top of Old Smokey," is one of the left-field pop hits of the '60s, having reached the Top 15 in 1963. The accompanying album is in the same vein, with Glazer and a banjo performing song parodies with a choir of kids. The remakes of familiar songs are given preposterous lyrics that constitute children's music only in the Shel Silverstein sense. For example, "Dunderbeck" is about a man who invents a meat grinder that turns all the neighborhood cats and dogs -- and finally Dunderbeck himself -- to sausage, and the tongue-twisting rendition of "There's a Hole in the Bottom of the Sea" is so crazy it could have come off a They Might Be Giants' children's album. You might be getting the impression now that On Top of Spaghetti is pretty cutting-edge for children's music in 1963, and it is, but it isn't unprecedented -- Homer & Jethro's "The Battle of Kookamonga" seems to have influenced, or at least have been a precursor to, the songs heard here, particularly "From the Halls of Montezuma (To the Shores of P.T.A.)." Before the tradition of great subversive children's entertainers like Soupy Sales and Shel Silverstein, Glazer was already making children's music that adults could enjoy as well.
