A BBC DOCUMENTARY is to be screened in August to celebrate the 30th anniversary of the recording of Queen's Bohemian Rhapsody at a Gwent studio.

Guitarist Brian May and fellow band member Roger Taylor spent a day at Monmouth's Rockfield Studios to mark the event.

Bohemian Rhapsody was recorded in Rockfield Studios in August 1975, and went straight to number one after it was released in the October of that year.

The six-minute epic remained at the top of the UK charts for more than nine weeks and has become one of the most celebrated songs in pop history.

Queen spent just over two weeks recording the track's parent album, A Night At The Opera, and extra dubs before the track went to another four studios for mixing.

During the BBC programme there are full interviews with Brian May and Roger Taylor, as well as a 'walk-about' the studios as they recall their time there.

Brian and Roger also re-recorded their guitar and drum parts from the hit, which are included in the documentary.

Chris Masters, a BBC spokesman, said: "We also travelled to Capitol Records in Los Angeles, where the producer of Bohemian Rhapsody, Roy Thomas Baker, unpicked the mix.

"Basically he stripped the song back and re-built it, which in itself is fascinating.

"We also have exclusive out-takes from the original recording sessions of the song, recorded at Rockfield in 1975."

Rockfield Studios has played host to some of the most famous names in the music industry since it was opened by Monmouth brothers Kingsley and Charles Ward 41 years ago.

Following the death of its composer, Freddie Mercury, a charity version of the single returned to number one in 1991. Bohemian Rhapsody has since topped numerous music polls, including the Guinness World Records (GWR) poll in 2002, in which it was named Britain's favourite pop single of all time.
