Longest gap between US & UK album hits
The Chipmunks
United States ()
Animated cartoon group The Chipmunks (USA), who first reached the US album chart on 30 November 1959, made their UK album chart debut with The Squeakquel on 6 February 2010 - over 50 years later. The personnel of the group remained the same, but the voices were provided by Ross Bagdasarian, Jr., the son of the original recording artist Ross Bagdasarian, Sr. (aka David Seville) (both USA).
