The Heaven is correct!

In Mr. Jordan According to Mr. Lennon A Candid Conversation. Julian talks about how he orginally thought about naming the album "Heaven" but then decided against it thinking "Nobody is going to ask me a sensible question on that!" 

Instead, Julian named Mr. Jordan after a 1941 movie called "Here Comes Mr. Jordan" in which a saxophone player is taken from earth before his time and then is given a second chance on life by Mr. Jordan. The movie was remade in 1978 as "Heaven Can Wait" in which the story is based around a football player vice a musician.
