Doh!!
It appears that my SQL is wrong.
All I needed to do was change my SQL to this ...
select
 distinct
  o.sql_text              "SQL text"
 ,s.username              "User name"
 ,s.schemaname            "Schema name"
 ,s.lockwait              "Lock wait"
 ,s.status                "Status"
 ,s.sid                   "Session ID"
 ,s.serial#               "Serial N"
 ,s.server                "Server"
 ,s.osuser                "OS user"
 ,s.machine               "Machine"
 ,s.terminal              "Terminal"
 ,s.program               "Program"
from sys.v_$session s
    ,sys.v_$sql o
where s.username is not null
  and s.sql_address=o.address(+)
