I had never heard the term mondegreen. Comes from a Scottish ballad:
Ye heilands and ye lowlands,
O whaur hae ye been?
They hae slain the Earl o' Murray,
And laid him on the green;
with "him on the green" being misheard as mondegreen.
Ye heilands and ye lowlands,
O whaur hae ye been?
They hae slain the Earl o' Murray,
And laid him on the green;
with "him on the green" being misheard as mondegreen.
