Great! It appears that you saw this at Barbican in London. Any news on a Blu-ray release?
I haven't seen the musical yet, only the 2012 UK film. I plan to eventually watch the 1995 musical version though. I recommend that you watch the musical.
It's nice to see some rare adaptations being found and released before they are lost or damaged. Many of the semi-famous adaptations that us fans are watching in the past 15 years were not easily available before then. However, some adaptations are having a different fate, for example the 1967 UK/1973 Mexico adaptations.
How does the 1925 France version compare to the high quality versions, for example 1934 France/1971 France/1973 Mexico/etc?
