"Mighty Ducks" star Shaun Weiss knows how to get a crowd excited ... leading an audience in an iconic 'Ducks' chant -- and tossing out signed gear.
The actor/comedian -- best known as Goldberg the Goalie from the 'Ducks' trilogy -- hit up the House of Blues in Anaheim for country singer Niko Moon's tour.
Weiss & Moon are both former addicts, and we're told Moon wanted to highlight Weiss' recovery -- pointing to him as a "hometown hero" of sorts -- since the Anaheim Ducks, who actually got their name from the film series, play real close to the House of Blues.
