"The sad thing is that everybody could have heard it by now if only the record label had been willing to do right by it. Porcaro was approached about the song for Xscape album, but he didn’t give his permission to use it. “
It seems songs are going straight to remix these days,” he told us. It was obvious this approach didn’t sit well with him. And while a fan in me would have loved to be able to buy the song and have it in my collection, I felt nothing but respect for Porcaro’s position. I thought that as a musician and a songwriter, he must understand how much the integrity of a song means to the artist. And as a colleague of Michael, he undoubtedly knows how much Michael cared about his compositions. “Less is more” was a principle he, too, cited as very important for MJ and Quincy. “Chicago 1945” is a great song that certainly doesn’t need any “contemporizing” and deserves to be heard and appreciated in its own right."
