Cream: From Hello to Goodbye in Less Than 3 Years

Jack Bruce, Cream’s Adventurous Bassist, Dies at 71. (The New York Times, 10/26/2014)

Cream enjoyed almost immediate success but did not last long. Friction between Mr. Bruce and Mr. Baker is the reason most often cited for the group’s breakup in 1968, after touring extensively and releasing four albums whose total sales have been estimated at 35 million.

In 1968, "Sunshine of Your Love" spent 26 weeks in 2 separate series of appearances on the Billboard Hot 100:

• January 13 - April 13:  74, 73, 69, 64, 53, 45, 37, 36, 43, 41, 60, 60, 60, 59.  14 weeks.
• July 6 - September 21 :  52, 41, 22, 18, 10, 9, 8, 6, 5, 11, 13, 25.  12 weeks.
