Labour stars belted out karaoke at the Mirror Party as Keir Starmer said we claimed Boris Johnson's "scalp" - and eyed up 10 Downing Street.
He spoke at the legendary Labour conference bash after the PM was ousted in a string of scandals including Partygate.
Mr Starmer told the crowd in Liverpool: "in many respects I think his scalp is yours.
"Because you started that work, you relentlessly pursued that work and he was always going to be brought down on character.
"You saw that, you pursued it in the same way you pursued stories, issues, investigations, absolutely holding all of us to account."
Labour's leader said this year's conference had a "different feel", with a "confident" party being "looked to to answer the questions and challenges that are there, uppermost for the country".
Shadow Health Secretary Wes Streeting, a future leadership hopeful, made a big show of his loyalty by singing Robbie Williams' Angels - and changing the lyrics to 'I'm loving Starmer instead'.
Deputy leader Angela Rayner teamed up with Shadow Work and Pensions Secretary Jon Ashworth to sing Journey's Don't Stop Believin'.
Shadow Levelling Up Secretary Lisa Nandy did Bon Jovi's Livin' On A Prayer with the live karaoke band.
And the Manc trio returned for a raucous rendition of Oasis' Don't Look Back In Anger.
Shadow Cabinet ministers Yvette Cooper, Emily Thornberry, Ed Miliband, Nick Thomas-Symonds, Pat McFadden and Luke Pollard were among hundreds of others at the bash.
The do in Liverpool's Revolucion de Cuba was sponsored by the Betting and Gaming Council, the industry body for gambling firms.
Keir Starmer warned "there's a long way to go" before Labour can win power in a general election - tipped for 2024.
Introduced by Mirror editor-in-chief Alison Phillips, he said: "We needed this opportunity, the Labour Party, to show the change we've made in the last two years.
"To show we've done the hard yards in the Labour Party, learned the lessons from 2019, and put ourselves into a position where we can confidently look at the electorate and they can confidently look back at us."
