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 , longstanding 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 , Europe and South America .
