vibes and harp

[Les]

Neil posted the Mirage press kit on his site. I was reading through and saw:

"As always, the instrumentation features Buckingham's guitars and Christine McVie's keyboards backed by the rock solid rhythm section of Fleetwood and bassist John McVie. Some slightly more exotic instruments were used as well, including vibes and harp, both played by Buckingham. Meanwhile, the vocals of Lindsey, Stevie and Christine have never sounded so lush, lovely and completely together as they do on Mirage."

First of all, is there an instrument called a vibe? What sort of instrument is it? I'm guessing a stringed one of some sort.

Second, which song(s) on Mirage contain Lindsey's harp playing? I hear the harp on D.W. Suite but maybe I just haven't listened to Mirage in a while, because I don't think I ever noticed harp on Mirage before. Ohhhh, wait, perhaps that's the plink plink sound on Empire State....
