There are plenty of other breath control exercises Dick - best to use one you don't intend to add to your reperoirs
As far as Bert is concerned - À chacun son goût
I found him entertaining enough without him being my favourite and his ability to adapt a song was unsurpassed
I have a collection of his superb radio programmes here - I can't think of another broadcaster who gave us access to so many unique, varied, thought-provoking and enjoyable examples of traditional song - you would forgive him anything in return for 'Folk Music Virtuoso, 'The Lament' and 'Songs of the People'      
Compared to what's on offer today... no contest, as far as I'm concerned
