Eminem - No Apologiez..Verses from which song?

[morbidenigma]

Next man was telling me Eminems verses on no apologies, are verses of his that have been on previous song/songs of his, and theyve just put the accapelas over a new beat.Can neone confirm this? and if so hook up me with the original songs the 'no apologies' verses were recorded over, or provide me the song names. SAFE..

i've got eminem and proof freestyling on some show and he does the "Everyones lookin at me" verse then gets into the second verse of "No Apologies" but im pretty sure i've heard it another time aswell
