Thank you for your inquiry. The commercial that you saw was for American
Original by Stetson Woman. The song titled 'With A Girl Like You' was
originally written and performed by The Throggs. For the purpose of the
commercial, different talent was hired to perform the song. Due to
contractual/legal purposes this information can not be released.
So, unless someone has a contact in the Coty/marketing/fragrance industry, looks like this one will remain a mystery.
