Young Holt Unlimited

Young-Holt Unlimited were a soul and jazz instrumental musical ensemble from Chicago, Illinois.
Drummer Isaac Holt and bassist Eldee Young, formerly members of Ramsey Lewis' jazz trio, formed a new outfit called the Young-Holt Trio with pianist Don Walker in 1966. They met with modest success, including the minor hit, "Wack-Wack", which charted at number 40 on the Billboard Hot 100.
In 1968, the group renamed itself Young-Holt Unlimited, and replaced Walker with Ken Chaney. Under their new name, the group scored a number three Hot 100 hit with "Soulful Strut", the backing instrumental track from Barbara Acklin's "Am I the Same Girl". "Soulful Strut" sold a million copies with the gold record awarded by the R.I.A.A. in January 1969, less than 3 months after the track's release.^[1] Follow-up releases would not match "Soulful Strut"'s commercial success, and the group disbanded by 1974, with Young and Holt returning to Ramsey Lewis' group by the 1980s.
