In a career spanning more than 50 years, Grundy came to prominence in the mid 1960s as the drummer of the English rock band the Zombies.
The family moved to Hatfield, Hertfordshire, where Ted worked at the De Havilland factory as an aircraft inspector and metallurgist; he was also an amateur violinist.
Rod Argent wanted to form a band and Colin Blunstone and Paul Arnold joined in early 1961, while all five members were still at school.
[7] In 1990, Blunstone, Grundy, and White briefly reunited as the Zombies with keyboardist and guitarist Sebastian Santa Maria to record the studio album New World (1991).
[8] To mark the 40th anniversary of the album Odessey and Oracle, the four surviving original members of the Zombies participated in a three-night series of concerts at London's Shepherd's Bush Empire Theatre between 7 and 9 March 2008.
[9] Together with the other three Zombies, Grundy performed a few songs when the band was inducted into the Rock and Roll Hall of Fame on 29 March, 2019.
