Tawl Ross was unavailable after experiencing either a bad LSD trip or a speed overdose, while Billy Bass Nelson and Eddie Hazel quit due to financial concerns.

From this point, many more musicians and singers would be added during Funkadelic's (and Parliament's) history, including the recruitment of several members of James Brown's backing band, the JB's, in 1972 – most notably Bootsy Collins and the Horny Horns.

The lineup stabilized a bit with the album Cosmic Slop in 1973, featuring major contributions from recently added singer-guitarist Garry Shider.

After first leaving the band, Eddie Hazel spent a year in jail after assaulting an airline flight attendant and air marshal while under the influence of PCP,[9][10] then he returned to make major contributions to the album Standing on the Verge of Getting It On (1974).

The ensemble usually toured under the combined name Parliament-Funkadelic or simply P-Funk (which also became the catch-all term for George Clinton's rapidly growing stable of funk artists).

Later in 1975 Michael Hampton, a teen guitar prodigy, replaced Hazel as the premier lead guitarist in Parliament-Funkadelic, and was a major contributor to the next several Funkadelic albums.

The title track spent six weeks at #1 on the R&B charts, around the time that Parliament was enjoying the #1 R&B singles "Flash Light" and "Aqua Boogie".

The album contains the fifteen-minute "(Not Just) Knee Deep" featuring former Spinners lead singer Philippé Wynne, an edited version of which topped the R&B charts.

The album was recorded by former Funkadelic members and original Parliaments Fuzzy Haskins, Calvin Simon, and Grady Thomas, who had left P-Funk in 1977 after disagreements with George Clinton's management practices.

This LP, notable for its heavy use of Thomas "Pae-dog" McEvoy's jazz horn, contains the track called "You'll Like It Too", which became a very popular breakbeat source for the hip hop community in the 1980s.

Clinton continued his P-Funk collective in the 1990s and 2000s, with a revolving stable of musicians, some of whom remain from the classic lineups of Funkadelic and Parliament.

In November 2008, Westbound Records released Toys, a collection of Funkadelic outtakes and demos from the Free Your Mind and America Eats Its Young era.

[15] Funkadelic's 1979 release "(Not Just) Knee Deep" in particular was sampled extensively by G-Funk artists, including placements on Dr. Dre's The Chronic, Snoop Dogg's Doggystyle, MC Hammer's Street Fighter OST, De La Soul's Me Myself And I and Tupac's All Eyez On Me.
