I'm utterly gobsmacked by that news. Though I've never met the man I think of him as a friend, a good and gracious man. This is just so sad for him.
Many of you may not know this but Bob was born in Australia and spent his very early years living in Sydney, he still has family here. Some years back I helped him out with some family history stuff and some photographic memorabilia. Through our correspondence I kind of feel we got to know each other a bit. Hearing such wretched news is simply awful.
