Songs about former band members

Hey, I'm very into the history of Yellowcard as part of my fandom and I wanted to learn from you all and make a playlist for myself. What is the total list of songs about former band members and who (if known)? The ones that immediately come to mind are Empty Apartment, One Year Six Months (I have no idea who those two are about specifically), and Five Becomes Four (famously about Ben Harper). So I know I'm missing a lot of history and figured I'd tap into the people here's knowledge. Thanks!
