Tri-ology

According to Dr Kermode if you are within 200 miles of Sun House Studios, Clarksdale then word trilogy, as used in the Elvis (the dead crooner) song An American Trilogy (which is to be played at Mark's funeral), is pronounced "tri-ology'.

This particular pronunciation is apparently evident in the Jonathan Ross documentary Viva Elvis. Beyond Elvis fans, this pronunciation is believed to be an aberration.
