Song Track: "S Club Party"
DVD Chapter: 19
Time Index: 1h17m19s to 1h17m25s & 1h20m13s to 1h20s17m
Due to the concert being filmed on two separate evenings and then edited together to appear as one performance, this slip-up has occurred as the result of very sloppy editing.
During the closing performance of the single S Club Party, on one of the two evenings of filming, Paul's headworn microphone was not working and he was given a handheld microphone. The other night he DID wear a headworn mic. They edited these two nights together, and because of the malfunction one evening, made this every obvious. At the two time indexes noted above, the editing is particularly obvious.
This also makes it quite obvious that the much of the concert's live audio track was deleted and re-dubbed to cover up the editing of two evenings' performances together.
