A success the world over, the musical «Grease», had its Swiss premiere at the Rheinknie Session in Basel (with Sue Mathys and Felix Martin in the main roles).  Although it had been playing on Broadway for years, very few people had seen this popular show live in New York. On the other hand, the film with John Travolta and Olivia Newton-John was a huge hit also here. «You’re The One That I Want» – many people relished reliving rock’n’roll memories at the Häbse Theater.
