Foo Fighters legend Dave Grohl will be hosting (yes, hosting) Jimmy Kimmel Live’s Halloween episode. Grohl is just one of various celebrity guest hosts filling in for Kimmel as he takes a short leave while his son prepares for heart surgery.

Jimmy Kimmel and wife Molly welcomed their second child together earlier this year. At just three days old, William Kimmel made it through a successful open heart surgery, prompting a health care speech from Jimmy Kimmel that went viral. At just six months of age, William must have another procedure and Jimmy Kimmel has chosen to be by his family’s side during this difficult time:

As a precautionary measure, the scheduled second heart surgery for Jimmy Kimmel's son Billy had to be postponed this week due to the common cold. Jimmy is very grateful to Shaquille O'Neal, Dave Grohl, Channing Tatum and Jennifer Lawrence for filling his very small shoes as guest hosts this week while he, his wife and children sneeze on each other.

Tonight, Dave Grohl will sit behind Kimmel’s desk tonight to interview actress Kristen Bell and rock god Alice Cooper, who will also perform live as a special Halloween treat. Grohl is somewhat of an experienced late night TV host, as the musician took over Chelsea Lately for an entire week back in 2013.

After the kids stop hammering at your door for more candy, watch Dave Grohl channel his inner Johnny Carson on ABC at 11:35pm/10:35pm CT.
