So, here is my idea for the new album cover. It might be too complicated, but it sounds fun...
Picture a kids birthday party. Two siblings (1 boy, 1 girl) around a party table (lame plastic party table cloth, confetti, balloons) one of them is clearly the birthday person. Everybody's got dopey party hats. You get the idea.
All the kids at the party (I guess as many as you want to add in the picture, maybe just the two siblings or maybe a small gathering of friends) look sad and depressed. The adults in the picture (I guess there should be a parent or two) look very happy. Maybe obvious drinks and other symbols of debauchery.
The birthday kid is about to blow out the candles on the cake and looks terrified.
Keith is making a crazy face at the birthday kid and giving big shooter McGavins.

Prominently against the back wall is one of those standard birthday banners with big letters that are joined together, each in a different color. You know the ones that normally say "HAPPY BIRTHDAY", but this one says "I'M DATING YOUR MOTHER".
Something like this bannner

Or maybe the album title should stand out a bit more, instead of the banner?
That's what I saw in my mind. Feel free to add in your ideas!
