text: The Queen and Princess Margaret recorded a special tape of favourite children's songs for the Queen Mother's 90th birthday in August 1990. Pianist Laurie Holloway was invited to Buckingham Palace by Princess Margaret to accompany herself and The Queen for the performance which was recorded on a cassette tape. The Royals recorded songs such as I know Where The Flies Go In Winter Time, which were incredibly popular when the Queen and her sister were growing up. The Queen was 64 at the time and Margaret 59. The Queen, left, and Princess Margaret, right made the recording for the Queen Mother, centre, in 1990 . The Queen Mother, centre right, was said to be delighted by the unique recording by her daughters . Mr Holloway told The Mirror that he arrived at the Palace and was shown into a room containing a piano and two microphones. He said: 'There was a sound engineer. We recorded each song in one take. The Queen has a nice, sweet tone to her voice.' Princess Margaret told Mr Holloway that the Queen Mother really liked the tape - although she had to go into her car to listen to it as she did not own a cassette player. Unfortunately, the unique recording was lost following the Queen Mother's death in 2002 at the age of 101. Meanwhile, it has emerged that the Queen Mother enjoyed a drink of gin at 11am according to a new biography of her favourite servant Billy Tallon. The Queen Mother enjoyed dancing with Mr Tallon, who she referred to as William. She preferred the music of the 1920s. He was responsible for delivering The Queen Mother her first drink of the day and if it wasn't strong enough she would remark: '‘William, do remember that when it comes to gin I have my reputation to consider.’ Pianist Laurie Holloway, pictured, was asked to accompany the Queen by Princess Margaret .
