The Who could soon reunite to release a new album.
Roger said: ''We're not going on the road next year - but we might do an album. The process involves identifying the songs that I can find in me [to sing] emotionally.
''He's [Pete] less adventurous than me - he says he's got all this semi-classical stuff, and I say, 'Look, we can do a jazz album, if it's the two of us, it's still The Who'. ''
The musicians could be set to reunite with drummer Keith Moon and bassist John Entwistle to record the follow-up 2006's 'Endless Wire' before heading out on tour next year.
Roger said: ''It's a symbiotic relationship that comes out in the music, between the two of us, whereas it used to be the four of us. We'll have to see.''
The 69-year-old singer says their arena tour in 2013, in which they played their 1973 double album 'Quadrophenia' in its entirety, took its toll on the band.
He said: ''We're definitely touring in 2015, that will be the last ever one.
''Not the last shows, but the last tour, as all the schlepping is a killer at our age. It takes six months to recover. Doing 'Quadrophenia' live knocked the f**k out of me, it's like going 10 round with Mike Tyson.''
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.
