need to find the name of a song urgently for a m8s funeral!

hi all, can anybody help me please out there? Im desperately trying to find the name of a track by Bob Marley but all I know is a few lyrics to the song i want and they are "excuse me while I light my spliff, oh god Ive got to take a lift from reality, i just cant drift"? Im not 100% on if these are the right words but are nearly there im sure! thanks to everybody and will love you forever if you can assist in this matter, many many thanks!

The song is called "Easy Skanking" by Bob marley .....
