At this point, they should just get their old material and other tracks that they worked on, and re-create them. I'm thinking songs like Bring It Back Home, Crash Diet (if possible), Too Much Too Soon, Sentimental Movie, Just Another Sunday, Ain't Goin Down No More, Goodnight Tonight, Killing Time, Rocker, etc. Settlement with the Arkeen estate and others would be required, but fuck it. I think it's worth it.
