From the Barclay James Harvest official website:
It is with great sadness that John Lees' Barclay James Harvest announces the passing of Woolly Wolstenholme. In recent weeks Woolly's mental health had taken a turn for the worse and sadly he took his own life on Monday 13th December 2010. As you can imagine, John, Craig, Jez and Kevin and everyone associated with the band are stunned that a shining light of Barclay James Harvest is no longer with us. In this difficult time our thoughts are with Woolly's partner, Sue. We would ask all of Woolly's fans to remember his incredible contribution to popular music and his unique presence on stage.
I just received the Mandalaband's remixed/remastered 1st 2 albums, where he played (ao) Mellotron on the 2nd....
He'll be missed a great deal.
