To Whom It May Concern is the tenth album by the Bee Gees. Released in October 1972, it is the follow-up to, and continues the melancholic and personal sound of its predecessor, Trafalgar. The album was recognised 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 solely 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 or rewritten for the occasion.
