all singing

Bruce just gave a deep sigh and watched the five people frantically think for a song. "I know one. Just follow my lead." He began snapping his fingers and tapping his foot along with the beat he made, "Woa, oh, oh. For the longest time. Oh, oh, oh. For the longest time."

The rest of the heroes on stage grinned and quickly realized the song he had in mind, hurriedly following suit and singing the background vocals, snapping their fingers to the beat.

"If you say goodbye to me tonight." Barry added in the higher pitched 'woas' in the background, much to everyone's delight. "There would still be music left to write."

On cue the five others grinned, "Ah, ah, ah…"

"What else could I do? I'm so inspired by you. That hasn't happened for the longest time." The others joined him in singing at the last line, Batman smirked, seeing the crowd's shocked faces over him actually singing…again. John tapped Batman on the shoulder, who nodded and let him take the lead.

"Once I thought my innocence had gone. Now I know that happiness goes on." The five continued to snap their fingers in a perfect beat and sang the background harmoniously. "That's where you found me, when you put your arms around me. I haven't been there for the longest time!" Once again they all joined in on the last line, enjoying the crowds smiles and shocked expressions. John stared at Shayera's beautiful face as he sang to her, he stepped back and let Batman take the lead role again.

"Woa, oh, oh."

J'onn cut in with his deep martian voice and added in the deeper parts to counter Barry's higher pitched voice, "For the longest…" They sang parallel to Batman.

"For the longest time. Oh, oh, oh. For the longest time. I'm that voice you're hearing in the hall." Superman added in the singular 'woos' with a smile. "And the greatest miracle of all. Is how I need you, and how you needed me too. That hasn't happened for the longest time." Diana stared up at them with a small grin on her face, knowing that Batman was slightly singing in her direction. The background vocals quickly changed over to 'bomp, bums' seamlessly, much to Aquaman's chagrin as he glared at Tempest for putting him in this situation. And proving that he knew surface dweller songs. "Maybe you won't last long, but you feel so right. And I could be wrong. Maybe I've been hoping too hard, but I've gone this far. And that's all that I hoped for." John, Superman, and Aquaman all joined in on the last line, which allowed John to take over again. And the background to change back to the original.

"Who knows how much further we'll go on? Maybe I'll be sorry when you're gone. I'll take my chances, I forgot how nice romance is! I haven't been there for the longest time." All six sang the last line. The crowd all were snapping their fingers with them and tapping their toes to the beat in awe of these six heroes on the stage, though mainly at Batman and John's voices. "I had second thoughts at the start. I said to myself, hold on to your heart. Now I know the woman that you are. You're wonderful so far, and it's more than I hoped for!" Batman smoothly intercepted and began to sing the final stanza of the song.

"I don't care what consequence it brings. I've been a fool for lesser things. I want you so bad! I think you ought to know that, I intend to hold you for the longest time." Barry added in the higher pitched notes, which Bart just giggled at. The men sang the title line together again, grinning (smirk on the Bat side) at each other before finishing the song, "Woa, oh, oh."

"For the longest…"

"For the longest time." Barry finished the song on his high note, as the audience exploded with applause and cheering for the six heroes. Aquaman quickly left the stage, trying to ignore the laughter coming from his old sidekick. Shayera gave John a hug and a kiss when he sat back down next to her, which he happily gave back to her. Diana just smiled at Bruce and leaned her head on his shoulder for a brief second before turning back to the stage to see who was next.

Batman just sighed again when he saw who was on stage; Tim, Bart, and Connor. Superman grinned and cheered for Superboy as he clicked on the song they were going to sing. Barry started punching Batman playfully on the shoulder before turning to Superman and doing the same.

"So I guess it's 'whose kid is better'?"

Batman just chuckled, "Don't you mean grandkid?"

Superman laughed, "Yeah. Grandpa."

"Hey! He is from the future!"

Batman just shoved him lightly, "okay Grandpa."
