Working from the BBC and MTV footage, several degrees of dramatic licence were taken, to release the concert on DVD. Many songs had their soundtracks altered for the DVD release, mainly in sequences where there were originally microphone problems. In one of those instances, Paul McCartney had re-recorded his failed vocals for "Let It Be" in a studio the day after the concert (14 July 1985) but it was never used until the release of the DVD. Also, in the US finale, the original USA for Africa studio track for "We Are the World" was overlaid in places where the microphone was absent (consequently, it includes the vocals of Kenny Rogers and James Ingram, two artists who did not even take part in Live Aid).
