SQL & PL/SQL :: Year And Month Query

I have two Queries.

Query 1:
SELECT DISTINCT YR FROM(
SELECT TO_CHAR( ADD_MONTHS (TRUNC (TO_DATE('01/01/2007' ,'DD/MM/YYYY'), 'YYYY'), 1*LEVEL -1) , 'YYYY')
YR FROM Dual
CONNECT BY LEVEL <= MONTHS_BETWEEN(TO_DATE(:to_dt ,'DD/MM/YYYY'), TO_DATE('01/01/2007' ,'DD/MM/YYYY')) + 1
ORDER BY YR
)

Gives the Output as
YR
****
2007
2008
2009
2010
2011

Query 2
*******
SELECT DISTINCT MONTH FROM(
SELECT TO_CHAR( ADD_MONTHS (TRUNC (TO_DATE('01/01/2007' ,'DD/MM/YYYY'), 'MM'), 1*LEVEL -1) , 'MM')
MONTH FROM Dual
CONNECT BY LEVEL <= MONTHS_BETWEEN(TO_DATE(:to_dt ,'DD/MM/YYYY'), TO_DATE('01/01/2007' ,'DD/MM/YYYY')) + 1
ORDER BY MONTH
)
Gives the Output as

MONTH
***
01
02
03

I want to combine these two. I need the output as
