(Set during Episode 11: 'The Dying Detective')

Beth's cell phone was a source of endless entertainment for their entire motley family. Sally described it as a laptop disguised as a phone. George and Nikola regarded it with keen scientific interest, Nikola claiming that he could build one himself with the proper materials, wondering how he had never thought of such a thing before.

The phone served quite an unexpected function for the Irregulars, however, from the moment Beth first played music on it for them. Most of them could sing well—they'd done so before as street performers and carollers. But Beth's music, a mix of 20th and 21st centuries, was unlike anything they'd ever heard before… and they loved it.

So this is what you meant

When you said that you were spent

And now it's time to build from the bottom of the pit

Right to the top

Don't hold back

Packing my bags and giving the academy a rain-check

Will was as bad as the rest of them, memorising lyrics instantly and singing those songs constantly with the other boys.

I don't ever wanna let you down

I don't ever wanna leave this town

'Cause after all

This city never sleeps at night

Beth never thought that, in introducing them to the classic songs of Imagine Dragons, she'd inadvertently inspired the very first boy band.
