I didn't know Pall Mall had a menthol & from wikipedia:
During the era of cigarette advertising on television and radio, the commonly accepted pronunciation of the brand was pel-ˈmel. However, after the Public Health Cigarette Smoking Act banned cigarette advertising, the pronunciation shifted to the phonetic form of pal-ˈmal. Older smokers who heard the commercials often still use the older pronunciation.
