Rabbi Benzion Shenker Z"L Sings His Famous Shoshanas Yakov 

Benzion Shenker is in fact singing the niggun -- he's the one to the left of the singer with the microphone . . . he's not the main singer so while the label may be misleading it's not inaccurate . . . and yes, the Shoshanas Yaakov niggun is not a Shenker original but one by Shaul Yedidyah . . . the first niggun on the clip, which i don't recognize, may be by Shenker

Ben tziyon shenker is not the one singi g - falsely labeled -

הולחן על ידי האדמו"ר הרב שאול ידידיה אלעזר טאוב זצוק"ל, בעל אמרי שאול ממודזיץ Composed by Rabbi Shaul Yedidya Elazar Taub zt"l, second Modzitzer Rebbe and author of Imrei Shaul The song, like many from Modzitz, is often falsely attributed to Rabbi Shenker z"l, who helped to popularize it.

It was Bentzion Shenker's Shoshanas Yaakov, but not really him singing it, was it ?
