So the Top 4 will be singing songs based around the theme of California Dreamin'- songs by Californians or about California. A very, very strange theme! The other song is "Free Choice"

Here are my suggestions-

Hollie- Part Of Me (Katy Perry)
Philip- California (Phantom Planet)
Joshua- California King Bed (Rihanna)
Jessica- Don't Speak (No Doubt)

Hollie- Whistle Down The Wind (Tina Arena)
Philip- Werewolf In London (Warren Zevon)
Joshua- Shackles (Mary Mary)
Jessica- Love On Top (Beyonce)

IF its a wide summer of love type theme I would LOVE to hear Hollie sing 'Whiter Shade of Pale' .(Annie lennox has covered it)....I suspect she will sing Katy Perry California Girls OR I just died in your arms tonight (Cutting Crew) OR Under the Bridge

Strange theme. On the Katy Perry theme, I'd like to see Hollie do Thinking Of You.
