Very different lyrics...

AVI linked to a Seekers song and I went hunting to see what else they did. Answer: quite a few hits, including one I only heard a time or two: The Carnival is Over, which is based on the tune from Stenka Razin.

Fortunately the Seekers didn't borrow the lyrics. True, water and parting of lovers play a role in both songs, but the situations and cultures differ a bit.

Stenka Razin led a rebellion against the Russian nobility back in 1671.
