Hi E!Welcome to the forum!
Planted said that he had read 'The Lord of the Rings'
'The Battle of Evermore' while it contains references to LOTR has many others.
Somewhat.
Only the title.That has to do with hippies,cops and roadies!
Tolkien influences were not Irish.They were Anglo-Saxon,Old English and Scandinavian.One more piece,King Arthur,at least as most know it was a Norman invention.
IMHO,it is the fire of Mount Doom,remember Mordor is east.
Because they are on horses?
But the 'truth' didn't come to Frodo in the end,did it?Only after Gollum played his part.
And of all the lyrics RP wrote about the LOTR,"Ramble On" comes close to the book.
"Leaves are falling all around,..."
Frodo finally left on his and Bilbo's birthday, September 22nd.
"Still,I'm much obligated,such a pleasant stay."
His waiting at Rivendale.
