British composers Barry McKay and Alan Morrison are recognized for their significant contributions to popular music, particularly through their work with the New Seekers. Active primarily in the 1970s, their songwriting partnership produced the iconic hit "I'd Like to Teach the World to Sing (In Perfect Harmony)," a global success that transcended its origins as a Coca-Cola jingle. Their melodic and accessible style helped define a sound that resonated with audiences worldwide.
