Back in 2003, Big Finish released Living Legend, which similar to a few other stories was originally a free gift for readers of Doctor Who Magazine. Since then, the short adventure has been made into a free download on their website, which I became aware of as I was scanning for the free stuff they have on offer. There’s quite a bit of to be found there if one is interested. A lot of them are samples of longer stories, but Living Legend is a complete, albeit short (a bit more than half an hour), adventure featuring the Eighth Doctor played by Paul McGann and his original audio-only companion Charley Pollard, played by India Fisher.
