About 9 years ago, Dave the Gnome correctly pointed out that the tune of "The Carnival is Over" is almost entirely taken from the Russian folk song "Stenka Razin", but incorrectly and unforgivably attributed the hit to the New Seekers. It was of course The Seekers, a vastly superior group. The New Seekers reworked Coca Cola ads. I think Tom Springfield did fess up as to where the tune came from, although sheet music you can download (both the Seekers version and Nick Cave and the Bad Seeds) still says "Words and Music by Tom Springfield".
