 Part Two of "Revelation Of The Daleks" was altered for its video release,  removing the song "Fire" by The Jimi Hendrix Experience (which could not be  used due to copyright problems) and replacing it with similar music, and also  inserting a short scene of Peri running to the DJs body. The problem of  unclearable music has plagued Doctor Who release, with scenes on the DVD  releases of "Spearhead From Space" and "Remembrance Of The Daleks" having to  be redubbed to remove music by Fleetwood Mac and The Beatles respectively.  The audio release of the episode "The Evil Of The Daleks" had to be edited to  remove two scenes throughout which Beatles songs could be heard.
