Yes, Ionesco is definitely someone we will be addressing in this series, both with The bald soprano, as well as other plays of his. The two were veritable rivals for the title of 'father' to the theater of the absurd and both wrote fascinating, though very different plays.
I agree, Gogo and Didi are desperately looking for some meaning, which might as well be God. I don't know how much Beckett disagreed with that interpretation itself or with the idea that he intended it to seem religious (which obviously, he did not).
Thank you for the comment!:)
