If you want to play this song exactly like on the record,you only need three things:A closed Hi-Hat(h),a snare-drum (s) and a bass-drum (b)...and two drum-sticks. During the song there are actually only two patterns: The main-pattern: The fill 1 + 2 + 3 + 4 + 1 + 2 + 3 + 4 + h-h-h-h-h-h-h-h-| h-h-h-h-h---h---| ----s-------s---| ----s----ssss---| b---b---b---b---| b---b---b---bb--| As it is looped in the studio-version,the drumming is very monotone. I think most of you prefer playing the live-version: In any case it is very important to play it tight. Roger sometimes opens the hi-hat for one or two 8-notes to bring a bit more variety into the pattern.He also uses a crash cymbal to set some accents(especially after the fills).In some live-versions Roger plays the bass-drum only on the upbeats(1 + 3) ,in others he plays it like on the record. Have fun!
