请问pink floyd 的专辑Wish.You.Were.Here中的Have A Cigar 是谁演唱的？

The lead vocals of the song are provided by English folk singer Roy Harper and is the only other Pink Floyd song aside from "The Great Gig in the Sky" to feature lead vocals by someone outside of the band.

On the original recording, the song's lead vocals are performed by an acquaintance of the band, Roy Harper. Roger Waters intended to record the part himself, but had strained his voice while recording "Shine On You Crazy Diamond", and David Gilmour declined to sing.

主唱竟然是英*国的民谣歌手 Roy Harper，上面来自wiki的材料指出，本来Roger想要唱的，但是声音在唱Sine on you crazy diamond之后就不好了（“Strained”）,另外David也拒绝唱这歌（我也觉得很奇怪）。
