Phish’s Jon Fishman will continue his support of Presidential candidate Bernie Sanders when the drummer speaks on behalf of the candidate at the Main Democratic Party convention this Saturday, the Associated Press reports.

Also speaking for Sanders will be former Main State Senator Troy Jackson, and Sanders’ opponent Hillary Clinton will be represented by former Massachusetts congressman Barney Frank.

Fishman has been supporting Sanders for the better part of the year and has previously appeared at events and spoke on his behalf. The drummer was also part of last month’s all-star Sanders event in Brooklyn that featured Kung Fu, Oteil Burbridge and many more. Watch a video of that performance below.
