I have zero issue with MSG - naturally occuring or added as "the white powder" (but not to become overly in charge) - but do think there is a celery flavor/odor in Lawry's. Perhaps it is a super low tier level of US spice blend like the wonderful spice mixes in Israel that Swisskaese shared - a back pocket helper. https://forums.egullet.org/topic/91663-eg-foodblog-swisskaese-the-israeli-table-not-just-felafel-and-or/page/2/ I've always loved that image and concept.
