Can anyone help me with finding the song on the unison advert, It goes something like" one is the loniest number"
Thanks a lot

the song, entitled "one" was written by Harry Nillson.
but it's been covered several times & I don't know whether the version used in the ad is the original.

hi thev answer one by harry the late harry nilsonn is correct
it was written by him and covered by others try john farnhams verdion its the best.
the line goes one is the loneliest number you will ever knoe followed by the number two
