Right on Pugno but it's been fixed on the Marston release, by D. Antsos, I believe. Patrick should check it out. Maybe he can do better.

Subject: Re: [ARSCLIST] Challenge Recordings with Wow?

All of the Raoul Pugno recordings of 1903 are afflicted with wow, thanks to
a badly calibrated turntable. It's a very fast effect, so it can be hard to
detect; it's more of a wobble:

The Victor of Part 2 of Ellington's Creole Rhapsody was mastered a little
off center, resulting in wow:

I have a UK Decca pressing of Ambrose's "Dodging a Divorcee" which really
has a problem in the last third.
