Too Much Heaven

From Wikipedia:

“Too Much Heaven” is a song by the Bee Gees, which was the band’s contribution to the “Music for UNICEF” fund. They performed it at the Music for UNICEF Concert on 9 January 1979. The song later found its way to the group’s thirteenth original album, Spirits Having Flown. It hit No. 1 in both the United States and Canada. It also rose to the top three in the United Kingdom. In the US, it would become the fourth of six consecutive No. 1s, tying the record set by the Beatles for most consecutive No. 1 songs.

Robin Gibb reportedly said on the Bee Gees’ interview for Billboard in 2001 that this track was one of his favorite songs of the Bee Gees. […]

Paul McCartney recorded this song in December 2004 in Sussex as a tribute to Maurice Gibb for his album Chaos and Creation in the Backyard but not released.

From Gibb Songs:

The second known track for the Maurice tribute album. Again this is a Bee Gees track with no obvious contribution by Maurice. This was recorded while Paul McCartney was making his album Chaos and Creation in the Backyard (2005).

Barry Gibb, in French newspaper Rock&Folk, November 2016, declared that the cover of “Too Much Heaven” by McCartney is one of his favorite Bee Gees cover.
