For little Portishead fans

Did you go to the concert last Friday? Was it fantastic? You brought out your Portishead records and have been listening to them on repeat ever since? If so, I have something that might interest you… Actually it's a little challenge… You know Portishead uses a lot of samples in their music (especially in the first albums). So would you be able to name the titles of songs from Portishead that use the following samples?
