Episode 4 - S1.E4

Roger fires his piano teacher for making eyes at his wife Veronica. Davina is shocked and she thinks he has only done it to show his more general contempt for artists. So she employs Greg, the piano teacher, to give lessons to Al. But when the young, sexy teacher starts making eyes at Davina behind Al’s back, she realises that there are a whole new set of lessons that she might want to learn.
