I was just listening to Nilsson's "Jump Into the Fire". Anonymous but wonderfully foundational bass line! Iconic, even. (BTW--this is the long version...listen to it about 3:00 in where the bass line moves downdowndowndowndown to one of the lowest notes I've heard. Happens again around 4:50.)
AH! Just checked Nilsson on Wikipedia and found this interesting info......"The third single, "Jump into the Fire", was raucous, screaming rock and roll, including a drum solo by Derek and the Dominos' Jim Gordon and a bass detuning by Herbie Flowers. The song was famously used during the "Sunday, May 11, 1980", sequence in the film Goodfellas".
