Wogblog reports that an expanded edition of John and Yoko's August 1972 One To One Concerts will be coming out soon using material from both shows - the 1986 album featured tracks from the afternoon show only whilst the '98 Lennon Anthology included three tracks from the evening performance.
Hopefully there will be a collectors edition that includes both concerts in full along with some of the rehearsals - there is a cracking performance of Working Class Hero that surfaced a year or so back on a radio station (see this thread).
