“Van the Man” wrote the song and first recorded it with his group, Them, before re-recording it as a solo artist. I think The Doors also did a cover of “Gloria”.

Both versions are great. Van sure could belt it out.

Every garage band worth a garage covered “Gloria” back in the day (tho not all recorded it). I can play still it in my sleep - we’re talking three chords here.(E, A and D in the most common key)
