Has any other band done what Genesis did in terms of lineup?

So over the years, the studio lineup of Genesis gradually got smaller. Instead of a departed member being replaced with someone new, their spot was filled by an existing member pulling double duty.

When Peter left, Phil took over on vocals while still playing drums. When Steve left, Mike took over on guitar in addition to his bass work.

Has any other band done something like this? The closest I can think of is when Joy Division became New Order, and Bernard took over on vocals in addition to his guitar work.
