The Allisons' entry for the Eurovision Song Contest, entitled "Are You Sure?", was the first single to be number one on the "NME" chart but not to reach the top spot on "Record Retailer"s chart. In total, sixteen songs failed to reach number one with "Record Retailer" but topped the "NME" chart. In 1969, after the BMRB chart was introduced, four songs topped the "NME" but not the BMRB chart. Notable discrepancies include "19th Nervous Breakdown", which reached number one for The Rolling Stones on the "NME", "Disc", and "Melody Maker" charts, topped the BBC's "Pick of the Pops" aggregated chart and was announced as number one on "Top of the Pops"; however, because it did not reach number one on the "Record Retailer" chart, it is omitted from the Official Chart Company's canon. The Beatles' "Please Please Me" suffered the same fate so, arguably, should be considered The Beatles' first number-one single. Conversely, Elvis Presley's double A-side, "Rock-A-Hula Baby"/"Can't Help Falling in Love", reached number one on all charts except "NME" because the entries were split by "NME" according to which song was requested when the shop returned its figures.
