A nice little love song in what sounds like a young Dean Martin style - and yeah! - this sounds weirdly familiar, like I've heard it before...
I genuinely think you could go to SF or somewhere hispter/nerdy like a college campus and sing this busker style, and really get a standing ovation from passersby
Quality tune!
I have to believe you've heard it before:

Then again... maybe I'd not have heard it much had the Beatles not covered it....
