For those interested, the YES album "Union", while not critically acclaimed by anyone (including the band), is very unique as it has not only Chris Squire playing on certain songs, but also features Tony Levin hammering away on what is clearly a Stingray with his funk fingers (you'll know which songs when you hear them!). Worth a listen just for the strange combination of unexpected sounds and tones for YES music. Bill Bruford on Drums with Tony too.
Will give it a try.
