I will say what I said on that thread. If you capture the gist of the song. Melody, swing, feeling. If you manage that and the audience enjoy it, so what if it’s not note perfect. Very few people will say , actually, in the second verse the original has a run down from an open E. You left it out. As said above. You check live versions of original songs and quite often the parts are not the same because they realise you have to simplify what you did in the studio because you have to leap about and pose, or sing , or for whatever reason.
