Finding my old site based on adsense channel

Old forgoten site of mine started getting some adsense clicks and earnings.
The channel related to that site started appearing in my daily adsense stats.

Problem is, I can't remember address of that site, since that is some old blogspot page which I haven't updated or visited for 1-2 years.

The only things I know related to it are: name of the adsense channel and it is on blogspot.
Is there any way I can find out address of that old page?
I tried googling some terms I think I used in that site, but couldn't find anything.

It will be nice to have part of the adsense admin where we can choose to list all addresses where specific channel appears, but I'm not aware of that feature, so please let me know if there is any woraround.
