UK Singles Chart records and statistics  The UK Singles Chart was first compiled in 1969. However the records and statistics listed here date back to 1952 because the Official Charts Company counts a selected period of the "New Musical Express" chart (only from 1952 to 1960) and the Record Retailer chart from 1960 to 1969 as predecessors for the period prior to 11 February 1969, where multiples of competing charts coexisted side by side. For example, the BBC compiled its own chart based on an average of the music papers of the time; many songs announced as having reached number one on BBC Radio and "Top of the Pops" prior to 1969 may not be listed here as chart-toppers since they do not meet the legacy criteria of the Charts Company. The following is a list of all the acts who are on eight or more UK number one songs "with an individual credit" (meaning, the main artist or named separately as a featured artist – being part of a group does "not" count towards an individual's total). Simply playing or singing on a single without credit will not count, or the top positions would almost certainly belong to session musicians such as Clem Cattini who is reported to have played drums on over 40 number ones. The record for most non-consecutive weeks at number one is 18 by Frankie Laine's "I Believe" in 1953. It spent nine weeks at number one, dropped down for a week, returned to number one for six weeks, dropped down for a further week and returned to number one for a third time for three weeks. The longest unbroken run at number one is "(Everything I Do) I Do It for You" by Bryan Adams, which spent 16 consecutive weeks in 1991. Below is a table of all singles that have spent 10 or more weeks at the top of the charts: "Note: Songs denoted with an asterisk (*) spent non-consecutive weeks at number one". Since the inception of the UK Singles Chart in 1952 only six acts have replaced themselves at the top of the UK charts with exactly the same billing (as opposed to any named artist, for example 'Cliff Richard and the Shadows' and 'The Shadows' have had back to back number ones on four occasions):   In addition, Ariana Grande is the first female artist to replace herself, and the first artist to replace herself at Number 1 for two consecutive weeks. Spice Girls became the first British music act and girl group to have their first six singles reach number one on the UK singles chart between 1996–1997 with "Wannabe" in July, 1996 to "Too Much" in December, 1997.
