We listen to this one every first of May. And it gets better every year.
This is one of the nicest songs written by the Gibb Brothers. The song was the only 45 released from the double LP "Odessa", an extremely underrated album.
Barry does the lead vocals and it was great: "First of May", now in a digital format.
By the way, the B-side "Lamplight" was also a great song but did not get much airplay on the radio.
