问一首外文歌是谁唱的 “sing, sing a song ....."

sing, sing a song
sing out loud
sing out strong
sing of good things not bad
sing of happy not sad.
sing, sing a song
make it simple to last
your whole life long
don't worry that it's not
good enough for anyone
else to hear
just sing, sing a song.
sing, sing a song
let the world sing along
sing of love there could be
sing for you and for me.
sing, sing a song
make it simple to last
your whole life long
don't worry that it's not
good enough for anyone
else to hear
just sing, sing a song
