Bonnie, this is Philip Ward's book which is very well worth buying! Philip organised the Troubadour bash a few years ago, also helped with the Barbican one etc. He's a good egg.

Shortish and unassuming book, not exactly a biography but a distillation originating from Philip's Sandy blog. Good standard of production, excellent pictures.

He takes his subject seriously, not descending to sensationalism or psychoanalysis, and he can write. Very good at teasing out the references in Sandy's songs - obviously these are his ideas but they seem pretty plausible to me.
