Sebastian Gardner first trained at The Oxford School of Drama, where he was nominated for The Andrew Lloyd Weber Award. He went on to train as an actor, playwright and theatre maker at East 15 Acting School, working under Uri Roodner on the highly accredited Acting and Contemporary Theatre course. During his time at East 15, Gardner represented the school for the Laurence Oliver Award, and later received the John Gielgud award. 'I Lost my Virginity to Chopin's Nocturne in B-Flat Minor' is Gardner's debut play. Upon its first sharing, 'Chopin's Nocturne' received the 'King's Head Theatre Stella Wilkie Award for New Writing' and 'China Plate Theatre's Best Debut Play'. The play was developed with performances at The New Wolsey, Ipswich and The King's Head Theatre before booking a run with Pleasance at Edinburgh Fringe in 2019. It later debuted at The Playground Theatre in August 2021, followed by a regional tour with Oxford Playhouse, Edge Theatre Manchester and Phoenix Arts Centre Hampshire.
