Just Older is the other 'classic' from Crush besides IML...I don't mind it being on the list forever. To me it's like the BOB or ITA of Crush.
Captain Crash is a nice bouncy poprock song but I'm beginning to get sick of it live. IGTG is lame. But all these aren't too hard vocally and that's why Jon kept playing them.

Sneaking Next 100 years from time to time is a great idea.
