Asim, Liza & Tim's confusing family dynamic

Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!

Asim, Liza and Tim made a song about 'Tasks to be done', with Asim's task being to find his son (Liza), and Liza's task to find her mum (Asim). Tim was dressed as Alex Horne and played the guitar.
