Frank Sinatra - (At Least a) Little in Love lyrics

We've always thought we were only fooling, But look at us now at least a little in love. We've always said that our heads were ruling, And I don't know how but here we are. This I'll admit is a fine how-do-you-do, But this might be I-discover-I'm-for-you. And just as sure as it's more than fooling. It's quite a lot more than just a little in love.
