Saying the wrong "Shir shel Yom"

Hi,

Each morning, we recite a special chapter of Tehillim [Psalms] corresponding to the day of the week; this is called the "Shir shel Yom" [Song of the Day]. If this takes place in a minyan, a kaddish recited by mourners follows.

If the chazan recites the wrong chapter of Tehillim, and then the mourners recite kaddish, the chazan should simply recite the correct chapter later, on his own, without a new kaddish. If the entire community recites the wrong chapter, then they should follow up by reciting the correct chapter, and a new kaddish may be recited afterward.

(Rivivot Ephraim 1:114)

Have a great day,
Mordechai
