I was referring to those who had not heard of him.
OK?
I assume they follow BoyZone or somesuch 
Hadn't heard of who?
Ned Sherrin - heard of him, radio a few times I think plus I was familiar with his TWTWTW stuff - my era
Matthew Arnold - never heard of him. Who the feck was he, and why was he important, and, more importantly, what, if any, is his link to Ned Sherrin? (so many commas in one sentence

)
P.S. I have a vague recollection of having heard of BoyZone - some kind of kids band weren't they?
