This is a hard one -- who, in your opinion, are the top 3 pop bass players that also provide lead vox (which is not an easy thing to do).

It is an impossible task, but here goes (in no particular order):

Paul McCartney -- of course. One of the pop pioneers. For decades has been writing bass lines that provide melody and syncopating with his fine vocal abilities -- for a great example, go back and listen to DRIVE MY CAR or SILLY LOVE SONGS.

Geddy Lee -- perhaps you do not prefer the timbre of his voice but, if you have ever witnessed this guy playing tough bass lines, singing lead vox and playing seperate accents with the keyboards or his feet on the Taurus pedals, the guy is a monster.

Jack Bruce -- one of my early favs. Another example of the type of guy needed to make a power trio go zoom.
