Who plays the second guitar in Pinball Wizard when played live?

I'm trying to learn Pinball Wizard so my band can perform it. I play guitar and I'm wondering how The Who played it live without a second guitarist. Pete Townshend played the acoustic guitar, but who played the electric? At first I thought maybe he used a pedal but that would be impossible in some parts of the song. I've watched live videos and Roger Daltry wasn't playing a guitar. Was John Entwhisle playing the electric guitar for live shows? Did they have a stand in guitarist? Did Pete do it somehow? any help and answers would be appreciated.
