Johnny Mathis should be included in 1978. He was 42 when "Too Much, Too Little, Too Late" went #1.
This is such a bleak top ten. The only song I really enjoy is Don't Let Me Down, which is sad because it's gotten so old yet it's still the best of the bunch. Ride, Send My Love, and Cold Water are decent. The rest aren't good, but they're not even bad enough for me to hate on them.
