During the performance, the band introduced new intros for several songs, such as 'I Don’t Love You' and 'Famous Last Words', enhancing the live experience.

My Chemical Romance made a significant return by performing their iconic 2006 album, 'The Black Parade', in its entirety for the first time since 2007 at the When We Were Young festival in Las Vegas on October 19 and 20, 2024.

The concert began with the album's opening track, 'The End', and followed the tracklist in chronological order, showcasing a nostalgic experience for fans.

Notably, several songs from the album, including 'Dead!' and 'Disenchanted', had not been performed live in years, with 'Dead!' last played in 2007.

Additionally, 'The Sharpest Lives' was performed for the first time since 2008, adding to the excitement of the setlist.

For the encore, My Chemical Romance delighted fans with two tracks from their earlier album, 'Three Cheers For Sweet Revenge': 'I’m Not Okay (I Promise)' and 'Helena'.

Overall, the complete setlist for My Chemical Romance's performance included all tracks from 'The Black Parade' along with the two encore songs, creating a memorable experience for attendees.

This performance comes after the band concluded their reunion tour in March 2022, having reformed in December 2019 and faced delays due to the COVID-19 pandemic.

Earlier this year, the band dismissed rumors of a reunion album after their Facebook was hacked, which had led to confusion among fans.

The band also featured new arrangements for 'Mama' and 'Cancer', with singer-songwriter Kayleigh Goldsworthy providing accompaniment on violin.

Their last new material was the surprise single 'The Foundations of Decay' in 2022, marking their first release in eight years since 2010's 'Danger Days'.

The festival also featured performances from other notable emo and pop-punk bands, including A Day To Remember, Jimmy Eat World, Simple Plan, and Dashboard Confessional.
