Adam Lambert and Queen will resume their tour on May 20 with a concert at Rock in Rio Lisboa. 

Brian May has now revealed to fans via a YouTube interview that it's inspiring to be performing with Lambert because he gives the band a new-found energy:

"I'm getting close to 70 now. It's quite something to be running around on a stage with [Adam], who is a young boy full of youthful energy and stuff. But I love it. I'm thrilled that we can still do this. How amazing! And it still makes people happy."

As previously reported, May also confessed that the 'Ghost Town' sensation is "a gift from god": 

"I feel so privileged that we can still do this. We spent half our lives building this legacy of songs and contact with an audience, and we can still be out there and doing it. And it's wonderful that we have Adam, because without Adam…You need an extraordinary figurehead, and we do have it in Adam. So it's a gift from God."
