...this rondo with Simon and Garfunkel is even better:
http://www.youtube.com/watch?v=nt4HZ7AKp1sI was born long after his heyday, so I've only discovered Andy Williams through YouTube. It's my understanding that he was considered off-puttingly middle-of-the-road even by the standards of the '60s (and especially by rock standards), but good grief, what a relaxed, supple delivery he had.
His Wiki entry is also interesting:
In the early 1970s, when the Nixon Administration attempted to deport John Lennon, Andy Williams was an outspoken defender of the Beatle's right to stay in the United States.
Williams was close friends with Robert F. Kennedy and Ethel Kennedy, campaigning for Kennedy '68 for President. Williams was present at the Ambassador Hotel when RFK was assassinated in June 1968. Williams solemnly sang "Battle Hymn of the Republic" at RFK's funeral, by request of widow Ethel. By August 1969, over a year after Bobby Kennedy's death, Andy and Claudine named their newborn son 'Bobby' Williams. The Williams' friendship with Ethel Kennedy has endured, with Andy even serving as escort to Ethel, during events in the 1970s. Although Williams was a friend of Bobby and Ethel Kennedy's, he said he is a lifelong Republican who grew up in Iowa singing in church choirs and feels right at home in Branson.
