Conflict of date on fourth monday only (apologies for my mistake) is better than first and third - but still not ideal

Personally, I prefer 2, but 3 is OK although hard to rationalise as the Old House is no longer the venue. Hazlitt of course, the man of letters, is strongly associated with Maidstone. If non-musicians (and non-singers) are feeling discriminated about, why not "the Hazlitt Club"
