It has been suggested that the percussive clicking noise heard throughout Kid For Today is the sound of a slide projector. [DC]
"Strawberry Fields Forever" by The Beatles includes a drum fill featuring a distinctive tambourine at 0:57; this seems to be the source of the drum loop beginning at 3:00 in Kid for Today (as well as one of the drum loops in Sequoia). The sample is slowed down slightly and only uses the left channel. [1]
