James Blake covered Billie Eilish's 'When the Party's Over' at his gig last night

Fans are already calling for a full version of the song to be released

Billie Eilish fans have already been treated to a special piano-based rendition of one of her songs this week - but how about another?

Following her gorgeous duet on 'Ocean Eyes' with Alicia Keys the other day, none other than James Blake has now done a stripped-back cover of one of her songs.

Blake, who is currently on a 'solo piano' tour, covered Eilish's song 'When the Party's Over' at his Los Angeles show last night.

Mobile phone footage from the gig shows him sitting at the piano and singing the understated track, taken from Eilish's debut album 'When We All Fall Asleep, Where Do We Go?' - and managing to hit her high notes, too.
