sed print flag

I have an input file that looks something like this:

Code:
....
key1: ABC
....
key2: DEF
....
key1: GGG
....
key2: HHH
....

The row of dots represents any number of lines that don't contain the strings "key1:" or "key2:" The strings key1: and key2: will always appear alternately as in the above example.

The sed command:

Code:
sed -n -e 's_key1: \(...\)_\1_p' -e 's_key2: \(...\)\1_p'

produces this output:

Code:
ABC
DEF
GGG
HHH

But what I really want is this output:

Code:
ABC DEF
GGG HHH

At one point I thought there was a upper case P flag that would print without
the newline character. That would do it, but at least with my GNU sed version 4.2.1 I don't see such a flag.

Are there any other simple ways to modify my sed command to produce the desired output?
