正确句子如下:
While Noble Sissle may be best known for his collaboration with Eubie Blake, as both a vaudeville performer and a lyricist for songs and Broadway musicals, he also enjoyed an independent career as a singer with such groups as Hahn's Jubilee Singers.
我想问一下未划线部分的主句中 as a singer with such groups as Hahn's Jubilee Singers是什么意思呢?最后一个as H's J singers修饰的是谁呀?谢谢
