In 1971, the group released "How Can You Mend a Broken Heart", which was their first American No. 1 hit. In October 1971, Gibb recorded three songs for the Barry Gibb Fan Club. One of the songs, "King Kathy", was released as a single on Lyntone Records. Gibb had remained a constant creative force for the group and, by 1972, had set aside the idea of a parallel solo career and was ready to devote full attention to the band. To Whom It May Concern was the last album recorded fully at IBC Studios and their last album arranged by Bill Shepherd who had worked with the group since 1964. Also in 1972, Gibb moved to Los Angeles to record in the Record Plant studio. In 1973, the Bee Gees moved to Robert Stigwood's RSO Records and released their first singles for Stigwood, "Saw a New Morning" and "Life in a Tin Can". Stigwood was not ready to give up on the group, but he did not believe in the musical direction they were taking. At the suggestion of Jerry Wexler and Ahmet Ertegun of Atlantic Records, Stigwood sent them to work with Atlantic producer and arranger Arif Mardin who produced the next Bee Gees album in 1974. After a United States tour early in 1974, the group started to perform at small clubs in England.
