I want to know the answer to the following question:
Which singer used Trident studios in addition to Queen and the Beatles?
All the background I'm provided with is that "This suited both parties at the time as Trident were expanding into management and Queen under the deal were able to make use of the hi-tech recording facilities shared by bands at the time such as the Beatles and Elton John to produce new material.". Is that enough to answer the question?
Answer: yes
