2014 promises to be a busy year in the world of classic rock. Here are a few things to be on the lookout for:

U2 -- A new album in the spring followed by a tour.

Bruce Springsteen -- New album, High Hopes, on January 14th. Still no word if he will tour the U.S., although he says he's keeping his options open.

The Moody Blues -- Second annual cruise in April, as well as U.S. dates in March, April, May and the fall.

Queen -- Planning an album of unreleased material, as well as a tour with Adam Lambert.

Eric Clapton -- Will be on the road, but no word yet on U.S. dates.

The Rolling Stones -- Will be on the road. Still no word on U.S. dates.

David Crosby -- Releases his first album in 20 years, Croz, on January 27th. He will support it with dates in January and February.

Rock and Roll Hall of Fame induction ceremony -- KISS heads up the Class of 2014 on April 10th at the Barclays Center in Brooklyn, New York.

Celebrate Gregg Allman -- An all-star tribute to the Allman Brothers' frontman on January 10th in Atlanta featuring The Allman Brothers, Jackson Browne, Vince Gill, John Hiatt, Dr. John and many others.

Paul Rodgers -- Releases The Royal Sessions, a collection of R&B covers, on February 4th.

The Beatles -- 50th anniversary of their first trip to America -- February 1964. This will be marked by a new box set and TV special.

Led Zeppelin -- Let's see if Robert Plant's comment that he has nothing to do in 2014 if Zeppelin wants to reunite results in a reunion. Jimmy Page is working on reissuing the Zeppelin catalog with bonus tracks in 2014, while Plant is working on a new album with his Sensational Space Shifters and John Paul Jones is working on an opera.
