Isn't it always the way. This photo and others from the National Geographic archives were auctioned off by Christie’s in an exclusive, online-only sale back in July and I only found out about it today
In 1969 Harry Nilsson made a guest appearance on the TV sitcom The Ghost and Mrs. Muir in an episode enitled 'The Music Maker'. During the episode Harry performed a version of 'Without Her' as well as a song he composed specifically for the show entitled "If Only". Unfortunately, both songs are interrupted either by dialogue, laugh tracks or both but working with a Sound Engineer I've done my best to create some relatively 'clean' versions. Given the quality of the source material perfect versions just weren't possible but what we ended up with is still an enjoyable listen.
Harry also performed an alternate version of 'If Only' offered below but for this, there was virtually nothing we could about the laugh track.
