In the absence of the 2020 TT and MGP_CTT races I've got hold of a set of historic TT CD sound recordings. They cover the years 1958-1968, so this won't be of interest to some, but they do make really compelling listening. I think they're re-packaged Stanley Schofield Sound Story recordings as the commentators are 1931 Lightweight TT winner Graham Walker and his famous commentator son Murray who really knew their stuff. Of course they can't replace the actual races but they include some cracking machine sounds, commentary and lots of rider interviews.
