Roger Daltrey

Despite not being owned by Daltrey, it was used as his vocal mic for the 1967 Monterey Pop Festival, as is visible in this concert footage of The Who's performance of "My Generation" at 0:11. As discussed in this video by Shure Creators (an official Shure YouTube channel), the McCune Audio company had loaned several microphones to the festival, including a number of SM56s.

According to the source linked above Roger has always used a variety of Shure microphones, though especially the SM58 he famously gives the windmill swing.

This microphone is assigned to The Who's lead vocals on Shure's official website.

Used for the vocals on "Who Are You", as mentioned by producer Jon Astley in this Sound on Sound "Classic Tracks" article.

"His voice was very good," Jon Astley confirms. "It held up when we put him under great strain, although he only did a lead vocal about once a week — it wasn't like he was doing two or three a night — and the two of us had great fun experimenting with different mics. I had cardioids and figure-of-eights, one above the other, to put his vocal into stereo by bringing it up on four channels... of course, you can buy a microphone now that does all that, but back then we had quite a hoot trying different things. The only thing was, it kind of made you sick when you listened to it, because if Roger moved slightly left or right the stereo image would move around in the speakers. I remember thinking 'I'm not sure whether or not this is a good thing,' so I ended up mostly using one Neumann U87 with a Urei 1176 on it.

During The Who's classic late 60s early to mid 70s period the bands main microphones were the Shure 565's as can been seen in this photo and many other pictures and live footage during this era
