The Radio Times archive shows that between 1934 and 1938, alongside regular broadcasts of services from Lichfield Cathedral, there were broadcasts of Ambrose Porter's organ recitals; dates of the broadcasts are listed on the radio page of our website.
In the Lay Vicars' vestry there is still a poster, albeit somewhat the worse for wear, exhorting us to attend his Saturday recital in July 1930.
However, this was clearly not a new thing. I recently rediscovered two handwritten programmes from my organ-playing grandfather's papers of Porter's Saturday recitals he attended as a 20-21 year old in the summer of 1926:
The programme for the June recital is written out in ink with what I believe is Porter's signature, having seen his writing previously; but the fading purple of the July programme makes it look as if it is just a printed duplicate.
