PG rated

The author of positively filthy ditties like 'Love Detective' and 'Glasgow Jubilee'. A man whose two main musical projects have been named after a sex toy and the middleman in a gay sex sandwich. A lyricist who once opened an album with the couplet "It was the biggest cock you'd ever seen / But you've no idea where that cock has been". Yes, I can think of likelier authors of children's books than Aidan Moffat...
