What the hell was that song about? (Featuring your requests!)

I've been obsessed with the meanings of the songs I love for a very long time but I must admit that some of them, are still a mystery to me. So, today, I'll investigate the story behind some 1960s songs that would get even English majors on their knees. 

Thanks to my lovely Instagram friends @a_shrey_in_the_life, @retrokyllikki, @retrodreamgirl, and @vinylbenjy for sending in their requests!
