因为疫情的原因，威廉姆斯大学2020年的毕业典礼改为线上举办。 作为母校今年毕业典礼邀请的唯一表演嘉宾。为了鼓励和恭喜学妹学弟们，王力宏站上了山顶，高唱了校歌《群山》。 这首歌是1859 年毕业的 Washington Gladden 的学生创作。最有意义的是，当时美国还没废除奴隶制，但他已经非常反对种族歧视，认为无论什么肤色人人都应该平等。 同时也把这首歌送给所有的毕业生，恭喜大家毕业了，愿大家前程似锦！
【音乐歌词(Lyrics)】
The Mountains 群山 (威廉姆斯大学校歌) - 王力宏
O proudly rise the monarchs of our mountain land
With their kingly forest robes to the sky
Where Alma Mater dwelleth with her chosen band
And the peaceful river floweth gently by
The mountains the mountains we greet them with a song
Whose echoes rebounding their woodland heights along
Shall mingle with anthems that winds and fountains sing
Till hill and valley gaily gaily ring
Beneath their peaceful shadows may old Williams stand
Till suns and mountains nevermore shall be
The glory and the honor of our mountain land
And the dwelling of the gallant and the free
The mountains the mountains we greet them with a song
Whose echoes rebounding their woodland heights along
Shall mingle with anthems that winds and fountains sing
Till hill and valley gaily gaily ring
