Of the Sex Sells songs, some were redone as a band and released on Crush and others (I Got The Girl, Real Life, Just Older, Save The World), some were released on the box set and Crush B-sides as Jon solo songs (Gimme Some, Hush, Crazy Love, I Don't Wanna Live Forever, Stay, Rich man living in a poor man's house and You Can't Lose at Love are all the same versions).
