There was money in all this, but it wasn’t easy for a new breed of music managers to get the formula right and to predict what — or who — young girls would go for. When, in the 1970s, a tidal wave of youthful female passion built up around David Cassidy, threatening to engulf him altogether, he himself was astonished, and many observers, particularly men, were gobsmacked. To many of them, Cassidy looked like a girly-boy, with his Bambi-like innocence and his penchant for knitted tank-tops worn over flowery cheesecloth shirts. Cassidy was pretty. Although he briefly experimented with an edgier, bad-boy image in his 1972 solo album Rock Me Baby, he soon reverted to sweet, baby-faced form.
