Zombies Are Walkin the Streets (original song)

I hope I'm posting this in the right section. Not to sure how to post mp3's to this site (if possible) so I will just post a link. There are a few songs on this link, but the last song is the uke version of 'Zombies are walkin the streets.' I'm working on a zombie musical. I have a few songs written for it and its in the rough draft stages. This song was originally written on my mandolin... but it sounds great on my oscar schmidt baritone uke. So I hope you enjoy... and feedback is an integral part of my songwriting.
On a side note this song is in the key of Bb.....

(i hope this link works ok... it seems to cut out at times. If there is a better way to post original songs that doesn't involve video, please let me know.)
