The 1971 - 1981 Volume 3 Box. Has What's Going On, Let's Get It On, Trouble Man, Here My Dear and 3 others. It was likely pressed at GZ, but I've had it on my wish list for a while and it dropped to $142 on Amazon.ca so...I have no self-control.
You have no self control? I bought an album of cat noises that comes in a jacket covered in fur. I HAVE LESS THAN YOU.
