From the wiki: “‘Just Dropped In (To See What Condition My Condition Was In)’ is a counterculture-era song written by Mickey Newbury (‘An American Trilogy’). Said to reflect the LSD experience, the song was intended to be a warning against the danger of using LSD. First recorded in 1967 by Jerry Lee Lewis for the album Soul My Way (he rejected its release as a single), the song became a hit for The First Edition (with Kenny Rogers on lead vocals) in 1968.
“It was Rogers’ first Top 10 appearance on the Billboard charts, and got the group their first national TV audience on The Smothers Brothers Comedy Hour. The song (as recorded by The First Edition) is also featured in a dream sequence from the Coen Brothers’ 1998 film, The Big Lebowski.”
