As far as I can gather, the Singers Club met on a Sunday evening from 1961 to 1963 (though, for a few months, from September 1962 to 12 January 1963, it met on both a Saturday and a Sunday).

Then, on Saturday, 15 February 1964, it opened at the Royal Hotel in Southampton Row.

Did it always meet on Saturday night after that? Or, at least, did it mostly meet on a Saturday night thereafter?

And, in what year, did the Singers Club cease to meet?

Can anyone help?
