John & Yoko / Plastic Ono Band with Elephant's Memory - Sometime in New York City (iTunes)

One of Lennon’s most derided albums, its arrival on iTunes gives you the chance to sample for yourself and try before you buy. It’s a long haul, a compendium of Lennon’s protest songs like Attica State and Luck Of The Irish. It was also his first solo outing to feature major vocal input from Yoko, like track two in this set: the boogie version of Sisters, O Sisters. Happy Christmas (War Is Over) is the video that comes with this set and it’s the version from the Lennon Legend DVD.
