Hawaiian Salt (from another newsgroup)


In another group, someone posted this question

<begin quote>

Just got the "Facing Future" CD by Israel Kamakawiko'ole. On the sleeve
notes he's credited with "vocals, ukulele, Hawaiian salt."
I see this quoted in enough places on line to believe it's not a
misprint,
but searching only finds "Hawaiian salt" used as a term for salt
found in,
er, Hawaii. But the placement in the CD credits suggests it's some
kind of
instrument.

Any thoughts on what Hawaiian salt is in this case?

thanks,
