this place is truly wonderful if you've not discovered that already in sifting through Lightfoot clips found here
check out the Great Interviews or the various Categories of other radio and tv video audio and video...if you come across any particular clip that you'd recommend, i'd appreciate it and so may some others...they certainly can transcend you back in time
i wondered if there is a similar link to other network archives that Americans might know of such as PBS, CNN, ABC, CBS, NBC or whatever? what about BBC or networks from Australia or beyond...live music video would be most welcomed but anything at all might be interesting to browse
