In August of 1967, the Brit-mod group the Small Faces released one of the most popular songs of their career. There are several stories behind the origins of Itchycoo Park, a song originally banned by the BBC because of its overt drug references. The true one seems to be that the song's title is based on the nickname of a public park known for it's scratchy nettles (Itchy Park).
The Small faces were formed in 1965 and broke up in 1969. Steve Marriott went on to form Humble Pie with Peter Frampton. The remaining members were joined by former Jeff Beck Group members Rod Stewart and Ronnie Wood and peformed as the Faces then Rod Stewart and the Faces until 1975. By then Stewart was enjoying phenomenal popularity as a solo artist and Wood was touring with the Rolling Stones.
Here's the original line up peforming Itchycoo Park.
