I really love Sandie Shaw's voice a lot. I haven't heard much of her original stuff but her covers are pretty great. I also have her Reviewing the Situation album where she covers 'Lay Lady Lay' and 'Sympathy for the Devil.' Every time I put the album on someone tells me that they love it. In 1984 she replaced Morrissey and covered three Smiths songs (Hand in Glove, I Don't Owe You Anything and Jeane.) I'm a pretty huge Smiths fan and these covers are also tops.
