As executive producer of the Grammy Awards, Ken ­Ehrlich oversees every element of the show. Thirteen days before the telecast (which will be his 32nd), this was his workday preparing for the 55th annual Grammys.

7:30 a.m. I had tweaked the rundown over the weekend and during the drive from my Thousand Oaks, Calif., home to the office in Encino I spoke with [Recording Academy president/CEO] Neil Portnow about his speech.

9:30 a.m. My first conference call was with Alicia Keys and Adam Levine. Over the weekend, we had decided on a mash-up of "Daylight" and "Girl on Fire." I had spoken with Alicia at the [Obama] inaugural and had [Virgin's] Ron Fair do a scratch track as a demo.

10:00 a.m. Brian Stonestreet, our scenic designer, brought me several looks that we made a few minor notes on: the set for the Miranda Lambert and Dierks Bentley duet and the one for fun. I also called Ed Sheeran's management to review the staging of his performance with Elton John.

10:30 a.m. Justin Timberlake sent in a rough track of the song he'll perform on the show and I played it for a few people in the office. It knocked me out.

11:00 a.m. We still have three or four openings for presenters and I went over potential artists with our talent booker, Chantel Sausedo. The show is still fluid at this point.

12:00 p.m. The most important promo ad for the show is the one that will air during the Super Bowl. Jack Sussman [CBS Entertainment executive VP of specials, music and live events] and his promo team clear the artists that can be announced with me.

12:30 p.m. Check in with [AEG's] Randy Phillips about the possibility of his client, Juanes, appearing, and double check with Frank Ocean's manager after seeing a report he is pulling out of the Grammys. Fortunately it was not true.

2:30 p.m. Our finale is still up in the air and one idea we are considering is a tribute to the Beastie Boys and MCA [the late Adam Yauch]. I spoke with LL Cool J about it and then with the Beasties' management.

3:30 p.m. I visited Justin Timberlake on a Hollywood set where he is shooting a video (right). We went through the look of the show and a breakdown of the music to finalize his performance.

7:00 p.m. Arrive home-it's probably the one day prior to the show I get home before 8 or 9 p.m.
