Pip Simmons Theatre Group: The Pip Simmons Theatre Group was formed in 1968.  Pip Simmons, the founder, served both as writer and director, but he was open to the ideas of others in the company, much of their work being devised pieces.  Initially London based, it was one of the first English experimental theatre companies but spent much of its time working in Europe where there was a more sympathetic financial and institutional network.  Simmons maintained the momentum of the group by taking a series of 'residencies' in theatre spaces around the UK and Europe, which was not a familiar concept at the time.  The group performed at the Mickery Theatre, under the nurturing gaze of Ritsaert ten Cate, along with contemporaries such as Mike Figgis, and The Wooster Group.  Pip Simmons has said of Ritsaert: 'Ritsaert made it possible for us to experiment.  He was learning with us, and he didn't hide it...I did my best work there in Holland, and Ritsaert stimulated it.  His stimulation wasn't just for one short period, though.  He provided the best stimulation, because he stuck with you through failures as well as successes.  He can't be compared with anyone else in Europe.'
