The Pete/Roy Ayers beat was an interlude on the Main Ingredient, I believe.
Showbiz also used it as an interlude on Runaway Slave w/ Fat Joe talking over it ("What's the word? 163rd!").
Funny, this is the 2nd interview I've had w/ a producer w/ in a couple of days making mention of that Dilla beat. Talked to Questlove for this RBMA event a few days earlier in NY & he told a story about being at Dilla's house when he constructed the "Little Brother" beat, patching it together from multiple parts of the "Ain't Got Time" original.
Thnx for posting the link here, Chan.
