Pop-rock newcomers Lawson have described Queen & Adam Lambert’s show at London’s Hammersmith Apollo last night as the best they’ve ever seen.

The British quartet, who last month reached No.4 in the UK charts with their debut hit, 'When She Was Mine,' took to Twitter to reveal just how much they enjoyed the rock legends’ final show with the American Idol runner-up.

Frontman Andy Brown, who was formerly in boyband Avenue with The Wanted’s Max George, said:  

"Adam Lambert and Queen at the hammersmith apollo. His voice is unbelievable. That was the best thing I've ever seen! #Queen&AdamLambert."

Bassist Ryan Fletcher, whose band release second single, 'Taking Over Me,' on August 5, was just as complimentary:

"Watching Queen at hammersmith. Already the best gig ever. Queen live with Adam Lambert singing is the best thing I've ever seen."
