From the wiki: “‘The ‘In’ Crowd’ is a 1964 song written by Billy Page and arranged by his brother Gene that was originally performed by Dobie Gray on his album Dobie Gray Sings for ‘In’ Crowders That ‘Go Go. Gray’s powerful Motown-like version, complete with brass section, reached #13 in the US and #25 in the UK in 1965. The Ramsey Lewis Trio recorded an instrumental version of the tune later that same year at the suggestion of a coffee shop waitress.
“Ramsey’s jazzy take, recorded live at Bohemian Caverns, a Washington, D.C. night club, reached #5 in the U.S. The British band, First Gear, also recorded a version in 1965 with Jimmy Page (Led Zeppelin) as a session guitar player. Bryan Ferry had a Top 20 UK hit with a Nouveau arrangement of ‘The ‘In’ Crowd’ in 1974.”
