Niall Horan welcomed Blossoms frontman Tom Ogden as a surprise guest during his Manchester concert on 25 September, performing the beloved track 'Charlemagne' together. The collaboration marks a notable moment for the song, which has retained its significance over a decade after its original release.

'Charlemagne' originated in 2015 as Blossoms' breakout hit and appeared on their self-titled debut album, which achieved Number One status in the UK in 2016. The performance occurred during Horan's 'Dinner Party Live On Tour' at Co-op Live, roughly a month after Blossoms commemorated the album's 10th anniversary with a special show at Manchester's Deaf Institute, where they notably opened their set with the track rather than closing it as tradition dictates.
