I get on fine with my mum and dad, but if they want to see the grandchildren, they come to me.
By bringing current events into the classroom, everyday discussion, and social media, maybe we don't need to wait for our grandchildren's questions to remind us we should have paid more attention to current events.
I spend a lot of time with the grandchildren. They love it when we sing together. It's fantastic to hear them, and they really can sing. I don't talk to them so much about 'Abba' and the past, but as they get older, they will become more aware.
I tour Europe a lot. They still have a love and a fascination with the basic thing about music - how it feels and that being the focus. I've got people bringing their kids. And their kids bring their kids. The grandchildren are getting selfies with their Uncle Al.
I was an early reader, and my grandmother, who as a child had been forbidden to read by a father who believed books to be frivolous time-wasters, delighted in putting her favorite volumes into her grandchildren's hands.
I am a Soviet man, and Yeltsin is a Soviet man - maybe our grandchildren will be different.
The human overpopulation issue is the topic I see as the most vital to solve if our children and grandchildren are to have a good quality of life.
