I don't know it, never played it but I just found it in Real Book II. All it is is a basic 1-4-5. Of course it can be jazzed up if you want but I just listened to a few versions of it and all I hear is mostly triads with a few 2-5's thrown in. Very simple, it's just another three chord blues.

This is a good discussion about an 11th chord but it's not in Lady Be Good.
