Due to the death of backing drummer Dennis Bryon's mother in the middle of the song's sessions, the group first looked for a replacement. The shortage of qualified drummers in the area prompted the group to try a drum machine, but it did not offer satisfactory results. After listening to the drum track of the already-recorded "Night Fever", the group and producer Albhy Galuten took two bars from that track, rerecorded them as a recurrent loop on a separate tape, and proceeded with sessions for "Stayin' Alive". This accounts for the unchanging rhythm throughout the song. As a joke, the group listed the drummer as "Bernard Lupe" (a takeoff on session drummer Bernard Purdie). Mr. Lupe became a highly sought-after drummer—until it was discovered that he did not exist.
