During a promotional video for Korg keyboards, Queen keyboardist Spike Edney may have revealed more than he intended. Now speculation is running wild that the band will tour the world with Adam Lambert as their singer in 2013.

Near the end of the video below -- interesting because it shows how many famous Queen sounds are created -- Edney talks about how he's used his new Korg. "I’ve used it for six shows now," he says, "looking forward to taking it around the world next year on a big tour. Fingers crossed!"

Edney never mentions Lambert, but the former 'American Idol' contestant received rave reviews from his performances with the band. Roger Taylor and Brian May both enjoyed working with the 20-year-old. Fans also appreciated Lambert stepping in for the late Freddie Mercury.

Lambert does have an active solo career, but has been suspiciously putting off plans for a solo tour to support his 'Trespassing' album. Most recently Lambert and the rest of Queen played together on June 30 in Kiev.
