The 2013 Martin Popoff short ebook about the making of the Sweet album, Off The Record.
If you want a whole book of stories from 1977 (including this one, but in shorter form), go pick up Ye Olde Metal: 1977. But specifically to satisfy the Sweet tooth, grab this one-bucker for the story of a crunching hard rock classic often forgotten when talk turns to Sweet, the spotlight usually being reserved for Give Us A Wink and the overlapped previous two. Yea and verily, I love writing these things just like a radio guy likes to spin records, namely to alert you to forgotten classics. Off The Record will not disappoint, as it's truly the last heavy Sweet collection welled up with all those Connolly vocals and inhuman harmonies you've grown to love.
