In the 1993 movie, the scenes of the traditional Mayday celebrations in Oxford, were filmed on the actual night and morning of April 30 to May 1, 1993. On Magdalen Tower were the actual choristers of the college chapel... no idea which house they used in that movie ?
The celebrations in 2019 started at 6am on Wednesday 1 May 2019 with the choristers of Magdalen College choir singing Hymnus Eucharisticus from the Great Tower. Hymnus Eucharisticus was composed in the 17th century by a Fellow of Magdalen and has been sung every year from the Great Tower on May Morning. I have attended this once it really is quite a magical moment.
