It appears Activision had forgot some songs when it issued the February release schedule of downloadable content for Guitar Hero World Tour, as developer Neversoft just announced a Southern Rock three-pack due for release today.

The songs are “Commotion” by Credence Clearwater Revival, “Gimme All Your Lovin’” by ZZ Top and “Black Betty”. The latter two are covers.

It can be noted that they did not name the artist who has performed “Black Betty”, as the song has been performed by a number of artists over the years.

Though no price point was mentioned, previous three-packs have sold for 440 Microsoft points ($5.50) and individual tracks for 160 points ($2).
