Run command after current command finishes?

Question

I use zsh, but bash-compatible would be nice.
I know I can do command1 && command2.
Is it possible to start command1, realise it's going to take a while to complete, but specify a job to run immediately after it finishes (presumably successfully)?
i.e., I want to run command1 && command2, at the point that I've started command1 on its way and forgot I wanted to specify command2.
Or is this not possible?
Thanks guys.

i still think he wants command2 to wait for command1 to finish.  i'd use similar job control plus a small function (which could live in bashrc if you do this sort of thing often):
//blue/0/~/ when_done() { while true; do ps $1 &>/dev/null || return 0; done; }
//blue/0/~/ sleep 20
^Z
[1]+ Stopped sleep 20
//blue/148/~/ bg
[1]+ sleep 20 &
//blue/0/~/ jobs -l
[1]+ 30771 Running sleep 20 &
//blue/0/~/ when_done 30771 && echo 'command2'
[1]+ Done sleep 20
command2
//blue/0/~/
But it's tied to a PID, so if command1 actually means 'commandA && commandB', that will fail, won't it?
/edit:
I think you're right; after some CLI testing, it seems both my over-complicated way and Procyon's identical simpler solution (I misread his initially ) will fail in the case of two initial commands.
//blue/0/~/ sleep 10 && sleep 10
^Z
[1]+ Stopped sleep 10
//blue/148/~/ fg; echo yay
sleep 10
yay
but i don't think that was the original question, was it?
