Irish singer Jackie Lee recorded a version for her 1968 album '' White Horses '' , produced by Derek Lawrence for Philips Records . A recording by the Dells of the song in a medley with " Love is Blue " reached number 22 in the US pop charts in 1969 . In 2004 Delta Goodrem sang the song in a TV advertisement for Tourism Australia that aired in many countries . Williams ' version was also the closing theme song for the Philadelphia children 's TV show , '' Captain Noah and His Magical Ark. '' The song has been used to teach children names of colours . However , despite the name of the song , not all the colours mentioned are actually colours of the rainbow ( the colour pink , in particular , is not ) , and they are not presented in order of the visible light spectrum
Love is Blue
L'amour est bleu
I Can Sing a Rainbow
