I found www.greatsong.net frustrating. I looked for "Amsterdam," Brel, but only a version by Isabelle Boulay seems to be there. It happens to be the same, but that is not evident from the printing, and many interpreters change the lyrics.
Search for "Il m'a vue nue" led to the version by Piaf, which differs from the Pearly-Chagnon song and Mistinguett version in some lines (although labeled as Mistinguett lyrics); also a few errors.
Moreover, information on composer(s) and date is lacking. Much advertising to navigate around.

Searching is much more difficult than in the late, great, paroles.net.
