Is it High-loon,Hay-Lun, Hay-loon, High-lun? What?

There was a thread about this recently. You might use the search at the top left of this page. It will take some practice to pronounce it correctly. Rich Galissini had us all twisting our tongues and vowels.

Thanks. Will do.

Try High-lwen.

Thanks, Laouuu.
