30 Days in the Hole

"30 Days in the Hole" is a song by English rock band Humble Pie. Released in late 1972, it was composed by the band's guitarist/singer Steve Marriott for the group's fifth album Smokin' (1972). The song received minor airplay at the time and failed to chart. However, it gained a following on album oriented rock (AOR) and classic rock radio formats, and consequently remains one of Humble Pie's best-known songs.

The B-side on its US release was "Sweet Peace and Time", while everywhere else the B-side featured "C'mon Everybody" and "Road Runner".

The song, a Steve Marriott composition, bemoans being arrested for possession of small quantities of illegal drugs, including cocaine; Durban poison, a potent strain of marijuana; and Red Lebanese and Black Nepalese, two types of hashish. "New Castle Brown" is often mistaken as a reference to Newcastle Brown Ale but actually refers to heroin also known as "Brown" or "Smack".

Guitarist Clem Clempson has said it is one of the tracks for which he would most like to be remembered. But the predominant group personality shown through by the song is Marriott's; so much so that, years later, Clempson was asked about efforts to reform the group without Marriott and said "It's a waste of time."
