David Gedge: "Keith returned from a holiday in America in
1989 with a cassette of ["Box Elder"] which we all liked and

It can also be found on the American version of Bizarro,
as well as Hit Parade 3.
The original version by Pavement can be found on the Slay

This question comes up because Pavement were not credited on
the US version, though they were on the UK version. Also the
copyright date on Westing is later than that of Bizarro,
leading people to believe that Pavement covered TWP.
