As you may remember, I used to conduct a traditional French music choir in my hometown. This shot was from a memorable trip abroad, to Wales, where we'd been invited to the famed Llangollen International Musical Eisteddfod folk festival. The tall and handsome man signing autographs like a celebrity was not only a strong tenor in the choir, he would eventually become family. His son next to him, wearing a white bonnet, ended up marrying my daughter, making him l'autre grand-père of my grandchildren — including my grandson who helps me write this here column!
