name of song and artist

since a long long time ago i'm looking for a song that i heard on a concert aired by mtv last year, althought it was last year i have no idea what year the concert was but it was a peace concert or a anti-war one

the lyric says sth like this:

do you remember the first/fifth/end(i'm not sure which) of september/december/november(i'm not sure which)

and then it says sth like
do you remember the sound of foo fighters,( or maybe food fighters)

it was sang by a man playing the piano and two girls were dancing in front of him


PLEASEEEEEEEEEEEEEEEEEEEEEEEE, i need to find this songggggggggggggggggggggg

it's driving me crazy, i've been searching for it for a monthsssss

bye

Earth Wind & Fire - September?

Also Marllion - Kayleigh

First one stresses the subject september a little more, the second one is more about "remember"

non of those songs are the one that i'm searching for but still thank you very much HEMA!!!!
