Us3’s extensive use of samples from the Blue Note Records catalog got the attention of Blue Note who surprised them with an offer for a record deal. (Richard Cook, Blue Note Records: The Biography, p226)
Main sample is from Herbie Hancock’s “Cantaloupe Island” (Blue Note, 1964)
A great version of Canteloupe Island by Herbie Hancock is the opening spot on the famous “A Night with Blue Note” concert in 1985.
