Sudden time on my hands and worried on a long-ago triv, I went and I looked and I verifized: Sammy Lerner is indeed the author of all *three* verses of "Popeye the Sailor Man" *and* "Falling in Love Again." He demised in the same year as the German Democratic Republic. No causal relationship has been established.
