First recorded (as “I Found You”) by Yvonne Fair & the James Brown Band (1962).
Also recorded by James Brown (1964).
Hit version by James Brown (US #3/R&B #1/UK #29 1965).
From the wiki: “‘I Got You (I Feel Good)’ was developed from an earlier Brown-penned song, ‘I Found You’, with a nearly identical melody and lyrics. ‘I Found You’ was recorded by Brown’s back-up singer, Yvonne Fair, and was released as a single in 1962 with little success.
“In 1964, Brown recorded an early version of ‘I Got You (I Feel Good)’ with a different arrangement, including a stuttering rhythm and prominent baritone sax line, under the title ‘I Got You’. This version appeared on the Smash Records album Out of Sight and was used in the 1965 film Ski Party, in which Brown lip-synched his performance. It was intended for a single release but was withdrawn due to a court order from King Records, with whom Brown was involved in a contract dispute.
“Re-recorded and released as a single in 1965 titled ‘I Got You (I Feel Good)’, the song would go to become Brown’s highest-charting song and is arguably his most widely-known recording.
