He had a heart of stonePolished hard all aloneHe had a heart of steelShining armour could not feelHe had a heart of sandWaiting for the tide to turnHe had a heart of leadSo heavy you could see the strainCHORUS:He never had the blues beforeâ¦He had a heart of goldPrecious heart never soldHe had a heart of clayHuman heart day after dayHe had a heart of glassFragile heart turned awayHe was a bolted doorTill someone found the key
