To Whom It May Concern is a 1972 album by the Bee Gees. Released in October 1972, it was the follow-up, and continued the melancholic and personal sound of its predecessor Trafalgar. The album was recognized as "a farewell to the old Bee Gees" as the album marked the end of an era for the group in several ways: it was their last album to be recorded at IBC Studios, in London, their last with conductor and arranger Bill Shepherd who had guided them since 1967, and their last under their first contract with Robert Stigwood. Some of the songs were old ones finished up or rewritten for the occasion (in the case of "I Can Bring Love"). To Whom It May Concern has sold approximately 350,000 copies worldwide.

After touring in 1971 to promote their previous album, Trafalgar, the Bee Gees worked quickly to complete another album. They recorded the song "Paper Mache, Cabbages and Kings" on 3 January 1972 which was the last song recorded with the Australian drummer Geoff Bridgford. He left the group before their tour of East Asia and was replaced on tour by Chris Karan. Recording resumed in April 1972 with a Robin song called "Never Been Alone" and a song Barry did on his fan club recording from 1971 called "I Can Bring Love". The drummer on the April sessions was a veteran session player, Clem Cattini. The first song recorded for this album was "You Know It's For You", a song written and performed by Maurice Gibb, on which he played guitar, bass, keyboard and mellotron. Karan did not participate with the Bee Gees on studio as Clem Cattini recalls:

The album was primarily recorded between June 1971 and April 1972 (except for "We Lost the Road", recorded in January 1971 during the Trafalgar sessions). The Bee Gees saved a non-album single, "My World", from the sessions which was released in January 1972, becoming a UK/US Top 20 hit. Shepherd's arrangements are relatively toned down and the background vocals sometimes seem to take the place of what could have been string sections.

The album was released in November 1972. Stephen Holden's contemporary review in Rolling Stone commentated that he felt the Bees Gees occupied "a very limited territory of pop music", dealing mainly in ballads of "momentary pathos", and that the album was "headphone mood music that makes no demands beyond a superficial emotional surrender to its perfumed atmosphere of pink frosting and glitter", and that the Gibbs vocal style had developed to the point where "they sound more like reed instruments than singers".Bruce Eder in a retrospective review for AllMusic feels the album makes for pleasant and satisfying listening, and is "one of their most fully realized works".
