I Believe

Frankie Laine had the big hit version of the song, which still holds the record for the most weeks spent at number one in the UK Singles Chart. However, that total of 18 weeks was not consecutive, as the hit had three separate periods at number one in the UK. For comparison the longest consecutive period at number one in the UK was 16 weeks by Bryan Adams with "(Everything I Do) I Do It for You" (1991), whilst Wet Wet Wet spent 15 consecutive weeks there in 1994 with "Love Is All Around".
During Laine's single's stay at number one, Queen Elizabeth II was crowned, Mount Everest was climbed and the England cricket team won back The Ashes after 19 years.
