The artist Yoko Ono, who turned 91 in February, has enjoyed a successful—if notorious—career over seven decades. She spent the seventies as the wife of Beatle John Lennon until his assassination in New York in 1980, and appropriately for British audiences, that part of her life forms the core of her current exhibition, 'Music of the Mind' at Tate Modern.

Few visitors to the Natural History Museum are aware of the ‘living exhibit’ in the grounds. However, this year, the low-profile Wildlife Garden celebrates its 20-year anniversary.
