The Little Theatre Guild, now known as the LTG, has been in existence since 1946 to represent the views of Amateur theatres across the UK. Penrith Players has been a member of the LTG for a long time, and people may have seen the newsletters and year book in the bar area. LTG creates regular newsletters which are now available on line, and here is a link to the current newsletter for March 2021: LTG Newsletter.
Enjoy.
