"'Til there Was You"

Remember this song by such as Anita Bryant and the Beatles? The title seems innocuous enough, but what's the subject of this clause? "You," right? The verb must be plural, ok? Then shouldn't the title be, "'Til there Were You"? I haven't been able to find anyone who disputes such logic, but the new title surely sounds weird. Oh, as an aside, "'til" is an abbreviation for "until." I don't care for the spelling "till," which seems to have little to do with "until."
