User blog:Johnpeel3904/Festive Fifty 1997

As all Peel-ites know, the Festive Fifty of 1997 had only 31 entries played on BBC Radio One. However on the rocklist website, they mentioned 19 songs that were not played (i.e. songs from number 50 to number 32). I want to know where were those 19 songs published ? Were they published on music newspapers such as the NME or did rocklist made up the list ?
