Lee's event begins tonight at Pontin's Prestatyn, North Wales.

Cale was announced for the festivals only a few weeks ago, but has now decided to cancel. In a statement, the legendary Velvet Underground musician says: "We did our best to believe in the organisers, in the end, they let us all down..."

Last month the Drive Like Jehu ATP 2.0 event was moved from its original home at Prestatyn to Manchester's Victoria Warehouse.

Stewart Lee curates ATP 2.0 15-17 April. The Drive Like Jehu-curated event takes place 22-24 April.

Tickets are on sale now.
