What microphones did the Beatles use for live performance during the 1960s?
The Beatles used a variety of microphones for live PA sound. Photos in the Shure archives show the Beatles using the Shure 545, the Shure 546, and the Shure 565. The same Shure models are also in photos from recording sessions. Note that the ubiquitous Shure SM58 was introduced in 1966; the Beatles ceased live performance in August 1966.

August 20, 1965: Chicago, Illinois, USA; Comiskey Park Concert; Vocal mics are Model 545; A25B metal stand adapters; A45 quick disconnect isolation mounts; foam windscreens secured with rubber bands. These mics were on loan from Shure and were to be returned to Shure after the tour. The mics arrived at Shure Service in a plain cardboard box with no indication they were from Beatles management. Not knowing the provenance of these microphones, Shure Service disassembled the mics and used the pieces as spare parts.

When the Beatles appeared on the Ed Sullvan Show, they sang into AKG mics. The exact model is not known, but we believe it to be the AKG D24B, or the AKG C60 with the W60 egg-shaped metal grill. We believe that the Beatles also used the AKG D120E on other TV shows.
Throughout Paul McCartney's solo career, he has preferred the Shure Beta 58 or SM58 as his live vocal microphone.
