"First of May" is a song by the Bee Gees with lead vocals by Barry Gibb, released as a single from their 1969 double album Odessa. Its B-side was "Lamplight". On the 1996 reissue of this single, its flipside was "How Deep Is Your Love" as the song re-entered the charts in Japan reaching #25. It was used as a B-side of "Melody Fair" in 1971 on the Melody soundtrack as well as in 1976 and 1980 on RSO Records. Also in 1980, sometimes, it was chosen as the A-side with "Melody Fair" as the B-side only in Japan. It was the first Bee Gees single after guitarist Vince Melouney left.
Barry's second young brother Maurice sang this song with Lulu in her concert.
