This is one of those Cole Porter tunes with lengthy lyrics;
it is rare to encounter a recording with every last verse/chorus.

Mary Martin introduced this song, in the same show as the song "My Heart Belongs To Daddy"
but "Most Gentlemen Don't Like Love" is not so closely associated with Martin as the other song.
"Most Gentlemen" has been recorded by everybody from Sophie Tucker to Betty Carter.
There is a feature film with Cole Porter song performances which includes "Most Gentlemen;" it is a film I have never seen.

The verse, rarely sung, rhymes "romance a lot" with "Lancelot."

One of the choruses quotes the "gentleman" as saying
"I'm yours forever / And I'll part with you never."

Thanks everyone for your responses in advance.
