It does look like Cliffe has succombed to a wig - and given his money, it should be a better one than that!
As to his sexuality - no-one is going to know until after his death.
Anyone famous who enjoys a public perfsonna but keeps their private life private is the subject of speculation which is exactly proportional to their fame and longevity as a public figure/
Ergo, people have wondered about Cliff for years!
As to his sleeping with women early on - that is no indication of long-term sexuality - especially for a pop star in the early sixties when being gay was still illegal.
We'll al know one day.
I had ,unch with Cliff at a TV shoot oncce, he was charming, and I would have loved to chat properly, but also at the table was the late Graham Starke who appeared (I think) in Summer Holiday, and unlike everyone else at the table, thought that should be be topic of conversation for the duration of the meal!
