World buffs from Vanilla raids

According to Wowhead, Nefarian's head, Onyxia's Head and the Heart of Hakkar all still gave world buffs during TBC. Songflower from Felwood was taken out on patch 2.4 however, but we're not on "patch 2.4" on this server yet.

Can someone confirm that these work on Outland?

An example, Rallying Cry of the Dragonslayer: Patch 2.1.0 (22-May-2007): Level at which characters will no longer receive this buff is upped from 60 to 63.

Oh I didn't see that part. Lame, alright thanks.
