WASHINGTON (AP) – Robert Bell of Kool and the Gang says he never thought the group would get as much mileage as it did out of the song “Celebration.” But he notes that recently it was used by NASA as part of the final space shuttle flight. Bell says the hit has surpassed the group’s expectations by far. But Bell reminds people it isn’t the group’s only hit – and songs like “Jungle Boogie” and “Summer Madness” are still very popular, too.
