Great video and it has to be one of the few lines I have heard the 5th string add anything of worth to the song, rather than a drone string the bottom up run really adds to the feel.
Love your study of jamerson, amazes me how many bass players have never sat down and listened, one even said, huh he could not play muse, I played him the break in Ill be there before the chorus, play that mate in F like jamerson did, then bring muse back to the table.
If one bass player laid down the foundations for the bass playing Riffs as opposed to root notes it was Jamerson, then Dunn I suppose...
