Stained Glass Window, St John's, Elford

Another bit of beautiful stained glass today - it wasn't what I intended to post, but as I arrived at the church the clouds opened and I dashed inside. St John's at Elford was restored in the 19th Century and it has some particularly fine floor tiles and stained glass windows - some of which are made from Flemish glass and were rescued from a Belgian Abbey. This one looks like it is depicting a wedding, so I'm wondering whether it is supposed to represent The Marriage at Cana.
