The Queen - Can’t Buy Me Love by the Beatles. For the Queen though she’d change the last word to “loyalty”.
The Queen - Push the Button by the Sugababes. This is exactly what the Queen tries to do with Eileen, and later with Jenny too. The Queen doesn’t always get the right button though - hence Eileen’s defection.
The Witch (also Brankaresh to Eileen and Roherum and weatherman) - I Love to Hate You can’t remember the artist but it sounds like Erasure. This is one for the Witch. Also Brankaresh to Eileen and vice versa. Also apt for Roherum and the weatherman.
The Queen - Sorry Seems to be the Hardest Word by Elton John. Certainly the Queen struggles with it!
Eileen, Jenny and Hanastrew - The Only Way is Up by Yazz. For Eileen’s, Jenny’s and Hanastrew’s trickier moments. Particularly apt for when Jenny begins to recover from PND.
The entire Fairy Kingdom! - It’s Not Unusual by Tom Jones. The entire Fairy Kingdom’s anthem!
