Effervescence Retro - May 21st, 1954

Effervescence recognizes the chart positions of The New Musical Express (NME) Hit Parade Weekly Singles Charts for this week in history. The same chart is recognized by The Official Chart Company, which compiles The Official UK Singles Chart today.

In The New Musical Express (NME) Hit Parade, the songs regularly shared a chart position due to finishing the week with the same sales figure (small sample size collated in the early days). For Effervescence continuity purposes, the song listed first on the source used will be given the higher of the shared positions. The only songs that can share a position are double A-side Singles. Both songs will be listed separately, with the same chart position for Effervescence continuity purposes for double A-Side singles.

The original The New Musical Express (NME) Hit Parade chart was presented as a Top 12. It has been modified here using the same week's Billboard Magazine (USA) Weekly Singles Chart (Top 20) and then the previous week's chart positions to expand the chart, as needed, to complete a Top 40 for Effervescence continuity purposes.

Clarity:

• The New Musical Express (NME) Hit Parade
• Billboard Magazine (USA) Weekly Singles Chart
• Any tracks that dropped out of the New Musical Express (NME) Hit Parade from the previous week
• Any tracks dropped out of the Billboard Magazine (USA) Weekly Singles Chart from the previous week
• Effervescence reserves the right at any time, ever, to make any adjustments or include songs from the time that did not chart in either the New Musical Express (NME) Hit Parade or the Billboard Magazine (USA) Weekly Singles Chart for this week
