Coldplay performed a Viola Beach track and were joined by Chris Martin's children at Glastonbury on Sunday evening.
The band paid tribute to the indie rock band with their song Boys That Sing after all four members - Kris Leonard, River Reeves, Tomas Lowe and Jack Dakin - and their manager Craig Tarry plunged to their death from a bridge in a tragic car accident in Sweden in February, according to the Daily Mail.
Frontman Chris Martin said the band "reminded us of ourselves in our early days".
He said: "We're going to create Viola Beach's alternative future for them and let them play Glastonbury for a song," before adding: "This would have been [Viola Beach] in 20 years."
The band played the track instead of David Bowie's heroes, which they usually perform, and showed footage of the late group performing.
In a touching gesture, Coldplay were joined by Chris' two children, Apple and Moses, on backing vocals - alongside two of their cousins.
Not only that, but his ex-wife and the mother of their children Gwyneth Paltrow was also seen in the audience, watching on with a huge smile on her face as the kids helped with the singing.
Looking cute, the youngsters sported sensible wellies and warm tops.
And Gwyneth - who famously 'conciously uncoupled' from her husband Chris in March 2014 - couldn't have looked happier to be a part of the gig.
The blonde Hollywood star, 43, flashed a huge grin while singing along to the meaningful track, acting the ever-supportive mother to her two children from the crowd.
Keeping it equally casual for the occasion, Chris wore his signature look which consisted of a short-sleeved T-shirt over a long-sleeved top - something he seems to wear for almost every single live occasion.

He also flew a flag that was emblazoned with the world 'love' as he delivered the set before a background of dazzling lights.
Speaking previously about plans for the tribute, a source said: "Coldplay always support upcoming bands and the new news of Viola Beach's sudden death hit them all hard as fellow musicians."
The special performance follows April's memorial concert held at the band's hometown of Warrington, Cheshire, North West England, where fellow indie stars The Kooks, The Zutons and The Coral performed on stage at the Warrington Parr Hall, where Viola Beach were due to perform before they lost their lives.
At the time of their tragic deaths, several music stars mourned the loss of the rising rock band including former Oasis star Liam Gallagher, The Stone Roses and Kasabian.
They all got behind a campaign to get the group's single Swings & Waterslides into the charts.
Martin also spoke out about Brexit before the Glastonbury slot.
Before the band hit the stage they posted on their Twitter account that "as a band we love playing in and being in Europe. This decision does not represent us or indeed most of our generation and the generation following us." in reference to the UK's decision to leave the European Union.
The band came out on stage to a recording of Charlie Chaplin's speech from the film, The Dictator, which has become a regular feature of their live performances, according to the Independent.
