“Saturday Night Live” once again served as a set-up for a Monday morning tour announcement: Pop-turned-Broadway star Sara Bareilles followed up her appearance on the late-night TV show with news of a 27-date fall trek, which will include an Oct. 16 stop at Xcel Energy Center in St. Paul.

Tickets for the Wednesday night performance go on sale Friday at 10 a.m. via Ticketmaster and the arena box office. Tour promoter Live Nation, which owns Ticketmaster and jacks up as many seats as it can to “platinum” prices, is once again not advertising set prices for the show.

Last week’s release of her first all-original album in six years, “Amidst the Chaos,” marked Bareilles’ return to the pop music world after she wrote the music and lyrics for and starred in the hit Broadway musical, “Waitress,” in addition to co-hosting last year’s Tony Awards and performing in the live TV production of “Jesus Christ Superstar.”

The “Love Song” hitmaker performed two of her new songs, “Fire” and “Saint Honesty,” on “SNL” this weekend.
