Sigh.

Wit, or sarcasm, as you choose, can be wasted on some.

Had I read the biography more than once there would have been a comma between 'thank you'and 'very often'.

Similarly, I use 'knew'- note the 'k' - as the perfect of 'know' as in 'acquainted with'. 'New', to me, connotes that which is fresh, ; or 'previously unknown' or 'not previously acquired'. Perhaps you omitted or elided the 'k' in your hurry to have a pop at me.

The phrase 'thank you very often' is a Northern humorous one, variants being 'thank you not enough' or 'thank you very glad'.

Being humorous, clearly it passed over your head.

I have said all I have to say about Ewan McColl - I have said all I know.

I am glad that you agree Hearsay to be inadmissible. Perhaps you might explain your use of 'party line', because that has gone over my head.
