Sorry,It is no more than jumping to conclusions,nothing has been proved,just because a song was only collected once,proves nothing,neither does the fact a similiar inferior song existed,it is a possibilty that Lloyds singer rewrote the song ,it is also possible that the two songs existed.
yes ,doubt has been cast ,but nothing is proven.inmy opinion Scholars should find better things to do with their time such as:
now lets look at the song of The Dawning Of The Day,and Raglan Road [Patrick Kavanagh]is there any proof that Kavanagh nicked or was inspired by the existing song?
