Thank you for posting this up Mike, very sad news about John Schroeder.
It brings back memories for me of buying my first ever single which was John Schroeder - I'm Going To Change in the late 1970's off a good friend, I know it isn't the most Soulful of songs but boy it certainly was my first step into getting the taste for Soul music which has never gone away from the night I had that record in my hands.
