Bobby Hatfield's solo at the age of 25 of Unchained Melody is one of the very best LIVE TV performances ever.
This was on the Andy Williams show in 1965—no remakes, no splicing, no sophisticated audio filters: just pure, raw, disciplined talent. Many considered it superior to the studio version - it makes women melt by the end of the song when he hits those high notes and it's been said this song and Bobby's voice is responsible for millions of conceptions.
