So I tried to make it serious. Ah well. Most of the lines fit the original songs, you just have to change the accents around a bit and it will sound normal.

Are you going to Bree’s Yearly Faire?
Athelas, kingsfoil; they’re the same.
Remember me to one who lives there
He once claimed Estel as his name.

Tell him to earn the Sceptre of Arnor.
Athelas, kingsfoil; they’re the same.
Or he will be booted out the door.
He once claimed Estel as his name.

Tel him to find the White Tree of Gondor.
Athelas, kingsfoil; they’re the same.
He knows it will not be in Mordor.
He once claimed Estel as his name.

Tell him to earn Gondor’s crown.
Athelas, kingsfoil; they’re the same.
And then our love will not get him down.
He once claimed Estel as his name.

Are you going to Bree’s Yearly Faire?
Athelas, kingsfoil; they’re the same.
Remember me to one who lives there
He once claimed Estel as his name.
