Agreed.

It's worth remembering that nobody knows the original composer of the "Superman" theme. While John Williams is credited with arranging the cinematic version, his arrangement was based on the television show theme. That theme was purchased sans-crédit from a French artist via a system intentionally architected to leverage the at-the-time gaps in international law to minimize Hollywood's cost burden for music scores.

To maintain this protection, they intentionally did not track the pedigree of the theme. This is a loss for history.
