Chiswick band The Tridents were formed in 1961 and are best known for containing Jeff Beck in their ranks from late August 1964-early March 1965.
The original formation was put together as an instrumental outfit, and played regularly at the Cavendish School Youth Club in Chiswick alongside The Detours with Roger Daltry on lead guitar and vocals.

Dear Nick,
Believe this clip includes footage of The Tridents live at Eel Pie in 1965. If it is, who in God’s name is playing guitar à la Beck?
Kind regards,
Peter
