On 16 November 1968, The Bach Choir attended a recording session in Olympic Studios with The Rolling Stones which became immortalised in their 1969 album Let It Bleed – the album went on to sell over 2,500,000 copies. BBC Radio 4’s looked back at this recording session in Add to Playlist last week – they interviewed our former singer Tessa Tulloch who was there and sang on the recording, too. She discussed what it was like to record with The Rolling Stones and to have Mick Jagger conducting her! Listen back to the episode on BBC Sounds here.
