Rock Choir has brought together 1,000 singers for a spectacular performance at London's Natural History Museum to celebrate Sir David Attenborough's 100th birthday.

Members of the Farnham-founded choir travelled from across the country to sing What a Wonderful World beneath the museum's famous blue whale skeleton, Hope, on Saturday, October 17.

The performance was recorded as a special birthday gift for Sir David, who turned 100 in May, inspired by his recitation of the song in the BBC's Planet Earth series.

Rock Choir was founded in Farnham by Caroline Redman Lusher MBE and has grown into a nationwide organisation with more than 33,000 members across the UK and Ireland.

The event, called A Night at the Museum, began with workshops and rehearsals at London's RHS Lindley Hall, where singers prepared for the evening's performance.

Members travelled from Farnham, as well as Glasgow, Edinburgh, Manchester, and London.

A choir spokesperson said: “Rock Choir is known for bringing people together through music and creating opportunities that extend beyond the rehearsal room.

“A Night at the Museum captured that spirit perfectly: a shared experience built around singing, friendship and taking part in something extraordinary together.”

After the Natural History Museum closed to the public, the singers gathered in its magnificent Hintze Hall for two recording sessions, each involving around 500 members.

Standing beneath Hope, the enormous blue whale skeleton suspended from the ceiling, they performed the Louis Armstrong classic in one of London's most recognisable buildings.

The occasion was made even more special by a surprise appearance from Ms Lusher, who welcomed members and praised their performances.

She described the sound of the choir as “breathtaking” and spoke of her pride in everyone who had taken part.

The ambitious event was organised by Rock Choir's events team, with choir leaders delivering workshops, conducting the performances and helping members prepare for the recordings.
