Drums on "Satan's Bed" were performed by Abbruzzese's drum tech Jimmy Shoaf. On the day it was recorded, Abbruzzese was in the hospital having his tonsils removed. Vedder and Gossard asked for Shoaf's help to get a drum machine working, and after setting it up, the pair asked Shoaf to perform the same beat on the drums. He is credited on the lyric sheet as "Jimmy". Months after finishing the initial recording sessions for "Vitalogy", Abbruzzese was fired in August 1994 due to personality conflicts with other band members. Gossard said, "It was the nature of how the politics worked in our band: It was up to me to say, 'Hey, we tried, it's not working; time to move on.' On a superficial level, it was a political struggle: For whatever reason, his ability to communicate with Ed and Jeff was very stifled. I certainly don't think it was all Dave Abbruzzese's fault that it was stifled." Jack Irons, the original drummer for the Red Hot Chili Peppers and Abbruzzese's successor, plays drums on "Hey Foxymophandlemama, That's Me". Gossard said, "Jack entered the band right at the end of making "Vitalogy". Jack's a breath of fresh air, a family man. Everybody had a strong sense of friendship with him immediately. He was just there to play drums and help out."
