 Foreigner's sound wasn't quite as heavy, and the band worked with then-unknown Thomas Dolby to program and play synthesizer.Dolby's work can be heard on "Urgent", along with a saxophone solo by Motown artist Junior Walker.The song entered the U.S. pop charts the week ending July 4, 1981, and reached #4 on the "Billboard" Hot 100 chart, holding that spot for the entire month of September.
