* Manfred Mann (1962-1969): The original band, fronted by Manfred Mann, disbanded in 1969.
* Manfred Mann Chapter Three (1969-1971): This lineup featured a new vocalist and a more blues-rock sound.
* Manfred Mann's Earth Band (1971-present): This is the most successful iteration, led by Mike d'Abo on vocals. The band continues to tour and record today.
So, while the original Manfred Mann lineup ended in 1969, Manfred Mann's Earth Band is still active, making it difficult to define a definitive "end" date.
