The 67-year-old rocker has confessed that while the band ''probably'' won't be taking to the stage at the world famous music festival this year, they wouldn't turn down the opportunity to take to the stage at Worthy Farm in the future if Adam Lambert - who has been acting as the band's front man in place of the late Freddie Mercury - is available.
When asked if Queen were set to perform at the festival later this year, Brian told BANG Showbiz: ''No probably not. Look these things get put on the table, it would be interesting to do Glastonbury if we were an operational unit at the time.
''You see this year Adam's off doing his solo work at the moment so it wouldn't have worked. You only look at things that are possible logistically at the time.''
The 'We Are The Champions' hitmaker has been performing with Adam, 32, and the band's drummer Roger Taylor since 2011, and is looking forward to him returning as Queen's frontman when they tour South America in September.
Speaking at this year's Ivor Novello Awards, which took place at the Grosvenor House Hotel in London today (21.05.15), Brain said: ''He's doing very well, 'Ghost Town' is his single, which is doing great. He's off doing his own thing and then he'll be back with us in September for some South American dates, including Rock & Rio.''
The star added he has been happy to offer his words of wisdom to Adam, who was the runner-up on the eighth season of 'American Idol' in 2009.
He said: ''I've given him plenty of advice, he's just a young boy really.''
Brian was joined at the prestigious award ceremony by his wife, Anita Dobson, as well as Ed Sheeran, who took home the Songwriter of the Year prize, Hozier, who won Best Song Musically and Lyrically for 'Take Me To Church', and Bob Geldof and Midge Ure, who were presented with The Ivors Special Anniversary Award.
There are currently five separate teams working on 'Game of Thrones' projects at HBO.
She's a big fan of the band and this week she got to perform with them.
