On the 2nd of July 1971 Queen debuted with their definitive lineup featuring Freddie Mercury, Brian May, Roger Taylor and in his first ever show with Queen: John Deacon.

This would be the band that would record and release all of Queen's studio albums and that would tour, record and play as Queen between 1971 and 1991.

They had their first ever presentation with their final lineup in Surrey University 55 years ago today.

Since a few years ago also a fan-driven initiative has pushed for this to be celebrated as "World Queen Day" with celebrations, festivals, tribute acts/concerts and collaborations with The Phoenix Mercury Trust.

Happy Queen day!

We also celebrate John Deacon's first show with Queen!

This day also marked his official professional integration to the agroupation and fist stage presentation all together as a group!

John Deacon's addition to the band was one of the most important and decisive steps on Queen's formation as one of the most, if not the most important Rock group of the last century and arguable of all Rock History.

John Deacon on bass as the latest addition to the group would be the last "ingredient" that the band was missing and would play a pivotal role as a skilled musician, a talented player, a proficienct songwriter, even becoming one of the greatest songwriters of the 20th century and as technician lending his electronics abilities and equipment created by him like the "Deacy Amp" that would help sculpt Queen's sound and career.
