Adam Lambert is currently on tour again with Queen, standing in for deceased frontman Freddie Mercury, and while passing through the Bay Area on Saturday and Sunday he posted a photo of himself in front of a Castro home where his mother lived in the 1970s.

Lambert posted the photo (which might have been on 20th Street?) to an Instagram Story, which was subsequently picked up and reposted by fans on Twitter. Lambert says it was the home of his aunt and uncle, and briefly his mother stayed there as well.

Lambert was also spotted by a fan in San Francisco — possibly in a hotel restaurant, though it's not identified — on Saturday.

The Queen show at San Jose's SAP Center on Sunday received a positive review from the Mercury News, which noted that while Lambert may be no Freddie Mercury, "it’s hard to imagine finding anyone better for the job."

Lambert himself acknowledges at the top of the show that, clearly, he's not Freddie Mercury and he isn't trying to be. "I fucking know — because there is only one Freddie Mercury," Lambert said.

The first tour with Queen featuring Adam Lambert happened in 2012, and this year's Rhapsody Tour is capitalizing on the success of last year's film Bohemian Rhapsody.
