In July 1998 'Beyond the Pale' contacted Bob Siebenberg, having unexpectedly found the lovely Barrie Wilson page at his own website. We were delighted to receive this response:
What a pleasure to find the Procol page, which is great by the way. I ordered the video that's available and a tee shirt with the first album artwork. If you know of any other footage available, preferably of Procol, but even of Joe Cocker with BJ playing the drums, I would snap it up in a hurry.
I also enjoyed the interview with Kenny White. [BJ's friend]. Very cool. We still get a Christmas card from Sue with an update of family doings and glad tidings. She's a very nice woman.
But what a trip to find all this information floating out there. Keep it up. I have tremendous respect for the Procol thing.
Please stay in touch, and thanks for referring to me on the page. I stand corrected on the year of BJ's death, if you say so. My family and I went to the funeral, but the year is a little hazy. Anyway, all the best, again stay in touch.
