Marty Friedman released a video of him in rehearsal.

This time, "Momoiro Christmas 2021" had many parts that paid homage to the "Momoiro Christmas" held 10 years ago at the same Saitama Super Arena.

One of them was a surprise appearance by Marty Friedman (former guitarist of Megadeth) to perform a guitar solo during "Moretsu Uchu Koukyoukyoku ..".

This time, Marty Friedman was celebrating his 59th birthday on the day of Day 2.

It seems that MCZ congratulated him as a surprise during the rehearsal before the show.

A video of the event was posted on Marty's Twitter page.
