Optimize Query Output

I have the following query: SELECT A.AttID , S.SessionDate , P.LastName, P.FirstName, A.Present FROM Attendance A, Sessions S, Participants P WHERE S.SessionID = A.Session AND P.Part_ID = A.Participant GROUP BY P.LastName, P.FirstName, A.Present, A.AttID I would like to have the output to have the P.LastName and P.FirstName values only shown once and the rest of the output printed... So instead of something like: +-------+-------------+-------------+-----------+---------+ | AttID | SessionDate | LastName | FirstName | Present | +-------+-------------+-------------+-----------+---------+ | 1 | 2004-10-30 | Apple | Robert | Yes | | 11 | 2004-11-06 | Apple | Robert | Yes | | 31 | 2004-11-13 | Apple | Robert | Yes | | 2 | 2004-10-30 | Bravo | Lisa | Yes | | 32 | 2004-11-13 | Bravo | Lisa | Yes | | 12 | 2004-11-06 | Bravo | Lisa | No | | 3 | 2004-10-30 | Beta | Elaine | Yes | | 13 | 2004-11-06 | Beta | Elaine | Yes | | 14 | 2004-11-06 | Delta | Alexander | Yes | | 35 | 2004-11-13 | Delta | Alexander | Yes | .... To have it look like: +-------------+-----------+-------+-------------+---------+ | LastName | FirstName | AttID | SessionDate | Present | +-------------+-----------+-------+-------------+---------+ | Apple | Robert S. | 1 | 2004-10-30 | Yes | | | | 11| 2004-11-06 | Yes | | | | 31| 2004-11-13 | Yes | | Bravo | Luz | 2 | 2004-10-30 | Yes | | | | 32| 2004-11-06 | No | | | | 12| 2004-11-13 | Yes | | Beta | Elaine | 3 | 2004-10-30 | Yes | | | | 13| 2004-11-06 | Yes | | Delta | Alexander | 14 | 2004-11-06 | Yes | | | | 35| 2004-11-13 | Yes | ..... Please advise I am running on mySql 4.0
