Last night, I attended my first ever sing-along…and it was at that sing-along where the 12-year-old Buffy the Vampire Slayer fan boy inside of me resurfaced and sang his little heart out.

For those unfamiliar with the series, Buffy aired from 1997-2003 on the WB and then later on UPN. In its sixth season, creator Joss Whedon decided to produce a brilliant musical episode called “Once More, with Feeling,” that makes Glee look like child’s play and thus giving fans the possibility of attending Buffy sing-alongs.

It's been years though, since the Alamo Drafthouse has been able to host a Buffy sing-along. Some say it's due to 20th Century Fox requiring high costs to secure rights to host a sing-along, but nobody knows for sure why.

In this case, it seems the studio let up a little once they heard James Marsters was interested in being a part of the sing-along during his time in Austin for Comic-Con. Eventually, everything got settled and the sing-along was on—just in time for the 10th anniversary of the musical episode's premiere.

The night started out in typical Drafthouse fashion with some funny clips from Buffy that included a montage of the original movie starring Kristy Swanson. Before long, James Marsters, sans bleached hair, was introduced on stage and in turn, introduced the first episode of the night, “Hush.”

It was clear the Drafthouse had some fellow Buffy enthusiasts because they knew exactly what would make the audience happy. For instance, the whole theater was instructed to scream alongside the slayer when she finally got her voice back (which we did) and when the Gentlemen’s head’s exploded, a shower of confetti exploded onto the audience.

Afterwards, Marsters came back on stage and hosted a quick Q&A with fans where we learned quite a few things about him. Some highlights include:

• Out of all the cast, he felt closest to Anthony Stewart Head, who also helped him with his British accent on the show.
• He’s in a band (Ghost of the Robot) that has a new album dropping on iTunes later this month.
• Despite having scenes with Charisma Carpenter in Buffy the Vampire Slayer and Angel, he felt he was finally able to really get to know her during their time on Supernatural this past year and had nothing but kind words about her.
• He can also mimic the sound of a lawn sprinkler remarkably well.

Then came “Buffy-oke,” where one lucky fan was able to reenact a melodramatic scene between Buffy and Angel from season two with James Marsters. Marsters gave a side-splitting portrayal of Angel while the fan voiced Buffy.

Finally, it was time for the “Once More with Feeling,” and it didn’t take long before the whole theater was singing right along with the Scooby gang. Bubbles were provided and used during Willow and Tara’s “Under Your Spell,” number, while fangs were provided to be worn during Spike’s “Rest in Piece,” number.

During “Walk through the Fire,” lighters were used in sync when everyone sang the line, “let it burrrrrn.” There was also a dancing bunny on stage complete with pyrotechnics which was entertaining.

Unfortunately, Marsters headed out just 10 minutes before the musical episode ended, and if there is only one thing about the night that was bad, it was that Marsters didn’t get a proper send-off.

Otherwise, the Drafthouse made sure to take advantage of such a golden opportunity in hosting a Buffy sing-along and certainly did not disappoint. They also hinted at the possibility of another sing-along, this time with Amber Benson joining…so fingers crossed.
