I spotted this in the Radio Times:
A pop-up channel on BBC iPlayer will be available from Friday 25—Sunday 27 June,featuring over 50 full Glastonbury sets from the archives as well as programmes selected by Jo Whiley, Lauren Laverne and Clara Amfo. Each day will have a theme: 1990s (Friday), 21st century (Saturday) and Legends (Sunday). BBC2 and BBC4 will also air classic sets across the weekend, including Radiohead from 1997, Kylie Minogue from 2019 and Fela Kuti from 1984, which has never been shown in its entirety before (check listings). A weekend of Glastonbury programmes will air on Radio 1, 1Xtra, Radio 2 and 6 Music, with more than 30 sets also available on BBC Sounds from 21 June.
