How many original members formed The Who?

How many original members formed The Who? Four: Roger Daltrey, Pete Townshend, John Entwistle, and Keith Moon.

The group developed from an earlier band called the Detours, formed in London in the early 1960s. Daltrey became the lead singer, Townshend the guitarist, Entwistle the bassist, and Moon joined as drummer in 1964, completing the classic lineup most people mean when referring to the original Who.

There is a small historical wrinkle: the Detours had earlier personnel, including drummer Doug Sandom and vocalist Colin Dawson. However, the internationally recognized original or classic Who lineup is the four-piece that recorded the band's landmark early albums, beginning with My Generation in 1965.

The four members shaped the band's signature sound: Townshend's power chords, Entwistle's melodic bass, Moon's explosive drumming, and Daltrey's powerful vocals. Moon remained with the band until his death in 1978, while Daltrey, Townshend, and Entwistle continued in later eras.
