Midge Ure admitted "it's different" as he detailed why Live Aid couldn't happen today.
The iconic event, which was co-organised by Midge and Bob Geldof, is marking its 40th anniversary this year.
Held at London's Wembley Stadium and John F Kennedy Stadium in the US, the concerts raised millions of pounds for famine relief in Ethiopia.

Fans were treated to a number of legendary performances from the likes of Queen, Status Quo, Mick Jagger, Phil Collins, Madonna and David Bowie.
Midge appeared on Good Morning Britain on Monday (July 14), where he fondly looked back on the memorable event with hosts Richard Madeley and Charlotte Hawkins.

"I feel nostalgic for my hair. It's amazing, isn't it? None of us can believe it's 40 years. None of us can believe we're still here looking back at this and the fact that it's celebrated today," the musician shared.
"It wasn't just a music event, it was a social event. It pulled people and the planet together, and focused people on a particular problem, which is the wonderful thing about music."
Midge also opened up on the event's unique nature that he felt would be hard to replicate today.
"There's enough trouble in the world to pull people together to try and sort. I think it's different, I think mobile phones have changed everything," he explained.
"I think people live a more splintered life, very difficult now to try and coerce people into looking at one particular problem because we're all living in our own little worlds.
"You can watch and listen to anything you want at any time day and night. Back then, we didn't have the internet."
Richard then noted that "there wasn't a mobile phone in sight," with Midge continuing: "I don't think they were there in 1985."
"It's been noted that no flags flying, no holding phones, people remember being there. Same when I did when I was a kid watching other bands... They were living in the moment."
An exhilarating new musical, titled Just For One Day, has begun playing at the Shaftesbury Theatre in London, and tells the story of Live Aid.
The production, which will close in January 2026, captures the excitement and history of that incredible day, featuring songs from the many of the iconic artists who made history at the event.
Good Morning Britain airs weekdays on ITV1 and ITVX at 6am
