Invitation wording - I need some help...

This is the wording I would like in the invites...
Are there too many ands?? I was also thinking of using the parents 1st names instead of Mr & Mrs

and
Mr. & Mrs. Glen ________

Darly Lyn
&
David Ira
exchange wedding vows
and become husband and wife
at half past ten in the morning

#2

Please join
Jack and Lois _________
Glen and Gerri _________
when their children
Darly Lyn
&
David Ira
exchange wedding vows
and become husband and wife
at half past ten in the morning
September tweltfh, two thousand four

The Sans Souci
Sea Cliff, New York

any suggestions are appreciated...

The wedding is more on the less-formal scale so I thought getting rid of Mr & Mrs would let people know that by reading the text

I like the first one but put a comma after 'their children,'
Other than that I like the Mr. & Mrs. it sounds nice. IMO

Thanks
I will put the comma there and redo it
I wasn't sure if it was too many 'ands'
But I guess not!
