Kerry Ellis, Alice Fearn and Jon Robyns are to star in a new West End Musical Drive-In event.
Launching on July 25, performances will take place at Troubadour Meridian Water in London.
Further dates and artists are to be announced, with the event set to run until late August.
West End Musical Drive-in is produced by Neighbourhood Events, the same team behind the West End Musical Brunch.
Each event will feature live performances from West End stars, with audiences able to watch from inside their cars or sat outside next to their vehicles.
