He might get a good run for his money, though, with Patsy Kline doing Willie Nelson’s “Crazy”, and of course the Paul Anka-penned “My Way” sung by, well, do I even need to say?
An old Victoria band - Shovlhed - did lots of fine covers, including this feisty rendition of King Crimson’s Great Deciever
Possibly already mentioned: “Summertime Blues” had at least two awesome covers, by Blue Cheer and The Who.
