This began as a radio play in the early 70's and was adapted to the stage in the late 80's. The story is terrific.
The play is structured moving back in time from 1972 to 1914 and then forward again from 1914 to 1972. It concerns three artists who have shared their lives together, including apartments and studios and the affections for one woman.
The play is funny, witty like so much of Stoppard, absurd and in concluding a bit sad. I would love to see this performed and recommend it as a read too.
If this was to be produced on stage I would say there are some complex technical necessities. Perfectly timed looping tape recorder and removeable balastrade/railing being the most central. If done well, as written, this would be a splendid show.
