Append original (source) Feature ID to undissolved Buffer attribute table

1) I have a bunch of source polygons for which I  have created undissolved buffer polygons.
2) I then want to do some calculations, e.g. length of line insecting the polygons, and add that information to the buffer attribute table
3) I then want to join those calculations to the source polygon

However, the feature ID of the source polygon is not appended to the attribute table of the buffer so this makes step 3 very difficult.  I thought a spatial join would be a workaround but I couldn't get it to work.

Does anyone have any idea how might achieve step 3 above?

BTW: there is a column called ORIG_FID in the buffer attribute table where I expected the FID of the source feature, but it is equal to one in all rows
