Yes of course Harry Cox and Walter Pardon, Sam Larner and Fred Jordan when recorded and over the many times recorded would initially have some consistency in what and how they sang songs in term of keys and ways ~ even if not exactly the same!

The young thruster "revivalist" singers by and large were/are younger singers and should be using their "own voices" ~ I am sure you know what I mean ~ and as has been said many of the younger singers do tend to blast out words and in doing so lose out on some of the intricacies of the source singers

Peter Bellamy used his "high" voice ~ whether this is a good thing is down to personal taste ~as has been said this requires for many either several beers or a shouty technique if you don't have PBs power and voice ~ what I am trying to say is PB is not necessarily a good "source" to learn from for everyone ~PBs style was personal and liked by many of course!!

For me revivalist singers should simply sing within their range using their own voice with regard to phrasing and methods adopted over many years by their source singer ~hence as PB did acknowledging their 'source' at the end of his song performance
