Official Singles Chart on 21/5/1969

From their own "history of the charts" Neil -

<<1969 – the BBC and Record Retailer join forces to revolutionise the UK’s chart compilation process. The two organisations commission the British Market Research Bureau (BMRB) to compile the UK’s charts on their behalf – these are the first true industry-recognised charts and are referred to as the UK’s “official” charts for the first time.
These charts are initially compiled from a panel of 250 record shops, who log their sales by hand and submit their totals by post.>>

Their chart is in a mess from the beginning of 1969 with many instances of the same record occupying two separate positions on the chart, several records indicated as re-entries when they have been in the chart for weeks, and at least one week where there are 49 records in the 'top 50' chart and no obvious way of telling which record has been omitted. A sad case of a company pooling several charts together as one; calling themselves 'Official'; and making a complete mess of things in the process.
