I think Adam did a great cover, but those performances were timed in preparation for the Queen Forever
release that year, so I think it is rather unlikely to hear that on this leg. Besides, Brian noted in the RS article that this is the 40th anniversary of NOTW
, so I think there's a good chance of hearing some songs from that album. If Brian is keen on this idea, I think that "Spread Your Wings", "Sheer Heart Attack" or "Get Down, Make Love" would be the most likely tracks to enter the setlist.
While it's doubtful that my idea would materialize, I think "There Must Be More to Life Than This" as a Freddie/Adam duet (AL taking Michael Jackson's parts) would work great live. Adam's certainly got the vocal chops and I think it would double as another nice tribute to Freddie during the show.
As for other songs, I may be in the minority, but I'd much prefer "Long Away" over "'39" during Brian's short set.
I heard that they rehearsed "Drowse" before the 2014 New Years' special, though I think the closest we'll get to Roger singing lead on one of his own songs is "TATDOOL", "A Kind of Magic" or a rehash of "I'm in Love with My Car" from the QPR days. If "Tenement Funster" makes its way to the set, I'd be in complete awe.
