A song from the album “Revolver” (or, in America, “Yesterday and Today”), “Doctor Robert” is a somewhat autobiographical song about the way that the Beatles’ touring schedule was somewhat fuelled by drugs.
The first single off his second solo album, “Uncle Albert / Admiral Halsey” was intended to be a nostalgic piece by McCartney. The uncle Albert of the title was his actual uncle, while Admiral Halsey was American Navy Admiral William “Bull” Halsey, who served with great distinction in the Pacific during World War Two.
The song – only the second single to be released by McCartney since the dissolution of the Beatles – quickly reached number one on both the US and UK charts, and acheived gold status shortly thereafter. It is notably one of only three singles to be credited to Paul and Linda McCartney – the following year’s album would be the first from Wings.
