Out of interest, people may not know that between 1927 and 1967 there where 3 Pro Grand Slam titles. This was in an era of amateur tennis when the best players would eventually turn pro. They would tour the world, mainly USA, in touring parties and play night after night, often indoors. Decent crowds came, it was a little like Coldplay or Beyonce coming to town for one night.

Several serious tournies where played and 3 of them became known as the Pro Grand Slam tournies - US Pro, French Pro and Wembley (ie GB) Pro.

The US Pro was played at various venues and on different surfaces, it eventually became the US Pro Championships at Boston in the Open era. French Pro was played at Roland Garros. Wembley Pro was played indoors at Wembley and became the Benson and Hedges Championships which I, for one, used to love and go and watch each year, attending the final when Michael Chang beat Guy Forget and staged the memorable McEnroe v Connors 5 set meltdown match when both players showed their worst tempers and behaviours and their best tennis.

the point though is that in 40 odd years of the Pro Grand Slam, two player won all 3 titles in one season - Ken Rosewall in 1963 and one Rod Laver in 1967. This was just before the Open era and his second official grand slam, and of course , the last player to achieve it. In 1967, the BBC also set up an event at Wimbledon called the Wimbledon Pro Championships with 8 of the top pros in the world. Rod Laver won it and , thus, it could be said he captured the full and only 4 event Pro Grand Slam to go with his 1 amateur grand slam, and his 1 Open era grand slam as well.
