Queen and Adam Lambert, “We Will Rock You” and “We Are the Champions” at the New Year’s Eve Concert in London 2014

Queen + Adam Lambert (sometimes referred to as Q+AL or QAL) is a collaboration between the active members of the British band Queen (Brian May and Roger Taylor) and American vocalist Adam Lambert. As with all other Queen performances since 1997, original bassist John Deacon has declined to participate in the project due to his retirement. This is the first long-term collaboration of Queen since the Queen + Paul Rodgers project ended in 2009.

The collaboration originated when May and Taylor appeared on American Idol in 2009 when Lambert was a contestant. They began performing occasionally in 2011, conducted a short European tour in 2012, and in 2014 announced a world tour, the Queen + Adam Lambert Tour 2014–2015 with dates in North America, Australia, New Zealand, Asia and Europe.

The band performed a special concert, Queen + Adam Lambert Rock Big Ben Live, which was broadcast live on BBC One on New Year’s Eve 2014 and New Years Day 2015. The concert was performed in the shadow of Big Ben in Central Hall Westminster, and the show paused for the chimes of the Big Ben in the New Year countdown and the firework display in London.
