Since I'm about to be leaving on a jet plane, you can take a wild guess as to which tune is the featured Song of the Day. Unlike these lyrics, I thankfully know when I'm coming back, but the posting will be a little quiet for just a week or two. Written by folk singer John Denver, "Leaving On A Jet Plane" was originally recorded in 1967 by the Chad Mitchell Trio (of which the then unknown Denver had replaced Mitchell two years prior), and later that year, this song was always recorded by Spanky & Our Gang (which I really wanted to post their version too but it's not on YouTube). Peter, Paul, & Mary also released a version on their album that same year, but it didn't become a big hit until they released it as a single in 1969. For this famous folk trio, it turned out to be their biggest (and final) hit, becoming their only #1 hit on the US Billboard chart. It also topped the easy listening chart for three weeks. In the late '70s, the song was used in United Airlines commercials. Here's a live performance by Peter, Paul, & Mary in Melbourne, Australia in 1968 (the sound quality is a not so great at the beginning but does improve for the rest of the song).
