In your (earlier) footnote re Sam Snead,  you stated 1946 at St Andrews, was his only Open appearance.   Snead played in the 1937 Open at Carnoustie and the 1962 Open at Troon where he finished approx 5th at 50 years of age.   I remember watching him on television at Troon despite the meagre coverage of the time.
 
+Thanks to Bob, I was able to correct the early statement that Snead did not return to play in another Open after winning in 1946. Funny how the mind can play tricks on.
