The prime minister entered the stage of Moving On Up by M People.
It was an interesting choice given the past few days of in-fighting and U-turns.
Lead singer Heather Small, who was raised on a council estate in west London, has a son who is a Labour councillor in Westminster.
She also used to attend Labour fundraising dinners regularly.
The first verse of the song might raise eyebrows given the past week:
You’ve done me wrong, your time is up
You took a sip from the devil’s cup
You broke my heart, there’s no way back
Move right out of here, baby, go on pack your bags.
And the chorus could be seen as a hint to Tory MPs who have spoken out against the PM:
‘Cause I’m movin’ on up, you’re movin’ on out
Movin’ on up, nothin’ can stop me
Movin’ on up, you’re movin’ on out
Time to break free, nothin’ can stop me.
