Heston Blumenthal - In Search of Perfection (Pizza)

[Son of Pam]

Unlikely but here goes;

In this episode, does anyone know the slightly maudlin slidey guitar piece that's playing as he checks out the San Marzano (?) tomatoes that grow at the foot of Vesuvius? Also what is the double bass tune that is playing when he is trying out the pizza stone for the first time and burns the top of it to shiit?

Thanks.
