Marla, being the expressive and enthusiastic woman that she was, smiled widely at the praise and nodded at the follow up to it. "Thank ya very much. It is a great song, and I'm sure you'll get it polished up just fine," she said confidently. He knew what he was doing, after all, and had already cultivated so many hits on the charts.
Although Marla didn't recognize the song just from the opening chord, John and Connor's reactions to it made it clear enough that it was a familiar one, so she wasn't too worried about being able to pick it up once they started playing it. Sarah took John's tickling and easing her away from the drum as something of a start to a game, and she giggled and moved right back to the drum again, slapping a hand on it as she stared up at him with bright eyes and a mischievous expression.
Marla narrowed her eyes at Colby, fighting back a smirk. "Donchya underestimate me, now," she warned him.
Emily had to laugh at that and add, "You really don't want to underestimate her. You can try, but I'm guessin' she'll give ya a run for your money."
