According to this
article, there are Deluxe Edition of the Lennon solo catalog due this year.
Reissues to follow Plastic Ono Band concert
The celebration of music created by John Lennon, Yoko Ono and their friends after the split-up of The Beatles is expected to continue beyond the reunion performance of the Plastic Ono Band at the Brooklyn Academy of Music on Feb. 16.
Since late last year, EMI has been working on a John Lennon reissue series to celebrate the 70th anniversary of his birth on Oct. 9, 1940. Initial plans call for the release of expanded editions of five of Lennon's solo albums and, for the first time, a box set of his commercially released work. EMI has not announced release dates of any of the reissues nor the specific albums.
EMI's Capitol Records reissued several of Lennon's solo discs between 2000 and 2004. The 1969 Plastic Ono Band's "Live Peace in Toronto" was remixed and reissued in 1995. The only Lennon box set was the four-CD "Anthology," a compilation of demos, home recordings and outtakes.
Unfortunately, there has been no news on this since (that I have seen). Anyone have any news on it?
