B b King 'blues on blues'

Hi David, I was just looking at your recent 'tip of the day' posts where you refer to a cut from 'blues on blues'. That album doesn't appear on the Australian iTunes Store, and apple have made it very tricky for me to check the US store. Just wondering if that cut might be available on a different record, or if the hook he uses is the same as on another recording of the song..

thanks and regards,

Dave
