Sometimes I come across a cover version that I've just got to list. I'll use this book to list those covers. Ideally I'd like to show my top 20 cover versions, but I'm not convinced I can find the originals and the covers to show. If I list a cover, it's because it has something to add. It doesn't mean it's better than the original. Sometimes they are, sometimes they're not. Sometimes they make the original passable.
