There was a Wembley tournament in 68 in which Rosewall beat Newcombe in the final. There was also a tournament in Paris, RG, in which Laver beat Newcombe in the final. I am pretty sure both were organized by Kramer.At Wembley in 1968, there were actually 3 pro tennis events. In spring in a NTL event, Laver beat Rosewall pretty badly in 3 straight sets. Then the BBC 2 event was played in April i think, where Laver again beat Rosewall in 2 sets. This event was billed as "World Professional Tennis Championshpis" and transmitted on tv as first ever pro tennis event to Germany. First time i actually saw those mythical, so long hidden pro players on tv. The Kramer event in autumn was a combined NTL/WCT event and so called by the trustful Lance Tingay, who makes no errors in those questions, also so billed in the 1968 World of Tennis yearbook. I saw pictures of Kramer in a line with those pros present. Kramer at that time was no longer the regular boss of the pros, that were McCall and Hunt. He was still operating as the organizer of the very important open Los Angeles South West Pacific event. Maybe he still had the copyright on it and brought the bill Tournament of Champions with him to London. Nevertheless, I don't see it as a direct follower of the TOC, which were played at Forest Hills 1957-1959.
