Wants are Simple, Needs are Few...

Does anyone know where this phrase comes from: "[Possessive pronoun] wants are simple, [possessive pronoun] needs are few"? (Or "were": one place it turns up is in obituaries.)

I first encountered it in a 1970 song ("Oscurita") written and performed by a pop trio, Cashman, Pistilli and West. (My references indicate that Al Martino covered the song.) But it goes back a lot further, very possibly to the 19th century.

Conventional search engines (Google, Yahoo, PCH) haven't helped me. The Internet Archive gets me back to 1904, in a magazine called Forest and Stream. (There are earlier listings shown there, but the dates are erroneous, except for an 1880 book called "India in 1880" -- which also shows up in Google Search -- where the two phrases seem to be used as part of ordinary sentences.)

It seems to me like something Henry David Thoreau might have written, but it's not in a list of his quotes online. More generally, it's not in my copy of Bartlett's Familiar Quotations, or a similar online collection.

Can anyone help?
