For those who had planned a London entertainment getaway before all hell broke loose, BBC 4 radio dramas can still shine a light on West End acting talents. California Dreaming of a ride up Laurel Canyon with local legends singing in your ears? Dial into SomaFM’s Left Coast 70s. Wanna hang on a hot Brazilian beach with a nouveau Girl from Ipanema? The internet radio station Paul in Rio can take you there. Whisper a few call letters into a smart speaker, summon a smartphone app, or tap a few computer keys to be whisked far, far away from your locked-down existence, transported across the country or half-way round the world, with nary a ticket to buy or passport to show. Suffering cabin fever? Need an escape? Internet radio can fling open the doors.
