WILLIAM COWSILL, part of the sixties singing COWSILLS family, has died at the age of 58.

Cowsill lost a battle with emphysema, osteoporosis, and other ailments in Calgary, Canada, on Friday (17FEB06).

The band - which comprised brothers BARRY, WILLIAM, BOB and JOHN, sister SUSAN and mother BARBARA - were the inspiration for TV hit The Partridge Family and had a number of chart hits including HAIR and The Rain, The Park And Other Things.

Barry was killed last year (05) when Hurricane Katrina struck his New Orleans, Louisiana, home.

William is survived by two sons.
