Thank you Phil ( Newport Boy) for those kind words.
For anyone interested in unusual time signatures in English music,There is an Alehouse was only one of many songs collected in Cottenham, Cambridgeshire by Ella Bull from their family servants and friends. A large proportion of the songs were in 5/4 time. Ella, a keen amateur musician intended to publish the tunes and songs via Lucy Broadwood of the English Folk Song Society, but was perplexed by the time signatures, so held up publication until she could be certain of getting it right. Ella tried to put them into the straight-jacket of orthodox time signatures such as 4/4, but was never satisfied with her attempts. It was Percy Merrick who came to her aid and suggested that they be written in 5/4 time, which, of course, solved all the problems. Her comment was " When I begain writing out tunes I did not know that 5/4 time was still extant".
Unsurprisingly, Ralph Vaughan Williams, who visited Charlotte Dann, one of Ella's sources, had no trouble at all in writing down the 5/4 tunes she sang including, There is an Alehouse.
