Mentioned in an official product description for the Yamaha P-250.

Yamaha has introduced the P250 Professional Stage Piano, the next member in the legendary P series family of Professional Stage Pianos. Ever since the P200 was first released over 5 years ago, musical legends like Michael McDonald, Keith Sweat, Tim Carmon (Eric Clapton ), Clifford Carter (James Taylor), and Steve Hornbeake (Faith Hill) have used it onstage and in the studio when they needed the absolute best piano sound available.

In the concert video "The Doobie Brothers: 50th Anniversary at Radio City Music Hall," captured by Gwen Shroyer on October 26, 2022, beginning at the 13:00 mark, the camera clearly shows Michael McDonald using the Hammond SK Pro 73-key Keyboard/Organ with 4 Sound Engines, positioned as the second keyboard next to his Yamaha Montage 8.
