Admit your ignorance - things you've only just realised/learned

I used to listen to 'Sounds of the Seventies' when Johnnie Walker presented it. I can't stand more than half an hour of it now that Bob Harris has taken over. The DJ is more important than the music.

I've just caught the end of 'Sounds of the Seventies' and I take it back. The programme's been ruined by the dirge Bob Harris plays. I've just remembered why punk happened.
