Neil Portnow and Ken Ehrlich are doubtless hoping for the continued good health of every prominent musician. That's just the kind of guys they are, of course. But also, they must by now realize that the upcoming 60th annual Grammy Awards already has enough all-but-mandatory posthumous tribute segments. With plans to include show elements keyed to the 60th anniversary and to the host city, New York, there's a limit to the number of dead musicians they can honor this year.

Here's a quick rundown of key music people who have died since last year's Grammy telecast.

Highly likely to rate a special tribute segment on the show

Chuck Berry and Fats Domino. These '50s rock legends could be saluted together. Grammy credentials: Neither was ever nominated for a Grammy, though their most classic tracks predate the inception of the Grammys in 1958. Berry received a Lifetime Achievement Award in 1984. Domino got his three years later.

Tom Petty. Grammy credentials: three wins, 18 nominations. Petty was MusiCares' Person of the Year honoree in January. Petty had two Album of the Year nominations in 1989, a rarity, for his own Full Moon Fever and Traveling Wilburys' Traveling Wilburys, Vol. One.

Gregg Allman. Grammy credentials: one win, nine nominations. The Allman Brothers Band received a Lifetime Achievement Award in 2012. Note: Fellow band member Butch Trucks, who died on Jan. 24, was included in last year's In Memoriam segment.

On the bubble (a special tribute segment is possible)

Glen Campbell. The only reason I have Campbell "on the bubble" is that the Grammys already paid tribute to him in 2012 when he received a Lifetime Achievement Award. He performed in a segment which also included Blake Shelton and The Band Perry. The Grammys may decide he's important enough to single out again—or they may decide they already honored him (and did it while he was alive and able to witness it, always a plus). Grammy credentials: six wins, 20 nominations. First country artist to win Album of the Year (By the Time I Get to Phoenix, 1968). Three Record of the Year nominations ("By the Time I Get to Phoenix," "Wichita Lineman," "Rhinestone Cowboy").

Chester Bennington and Chris Cornell. These rock stars who took their own lives could be saluted together. Grammy credentials: Bennington: two wins, six nominations with Linkin Park. (One of those noms was for Best New Artist.) Cornell: two wins, 14 nominations with Soundgarden, Audioslave and on his own.

Al Jarreau. Jarreau died on Feb. 12, the date of last year's telecast. They worked in a quick mention on the show, but he didn't get his full due. Grammy credentials: six wins, 19 nominations (very nearly equaling Campbell's tallies.) Breakin' Away was an Album of the Year nominee. Jarreau was part of "We Are the World," a Record of the Year winner.

Walter Becker. Grammy credentials: Three wins, 10 nominations. Steely Dan received three Album of the Year noms (for Aja, Gaucho and Two Against Nature, which won).
