Hey Shipwrecked! Your best bet to get Harmony is Tower records.That's where I got mine. It's been 2 months today (or yesterday now that it's after Mid. here in AZ)that I go it and I'd be surprised if it was not still available.
Cross city or county lines if you have too. Otherwise,AMazoon or E-bay is your best bet.
Unless you have a store like we do here in Phoenix that deals with old & new and rare! Ours is called Zia and the one nearest me has 1 copy! Glad I didn't wait for it to get there. Happy hunting,later!
