Jaskier roll his eyes after his brief conversation with Imbert and sarcastically remarks
"Another time perhaps."
Jaskier hears his name wafting above the crowd along with the word "ballad" so he shrugs and says
"Alright, alright, guess its time to get to work, 'tis getting late anyways."
and he threads his way among the crowd to the bar and orders two whiskeys. Zanben, close enough to hear him, says
"Did you order one for me?"
Jaskier replies
"No dear Zanben, I'm merely warming up!"
Jaskier gulps down his first whiskey and scowls
"Yup, very warm indeed!"
and proceeds to drink the second, leaving a small amount of amber liquid in the glass. Jaskier shudders for a moment and suddenly, as if a switch had been flipped, his demeanor changed and he carried himself more grandly than ever. His voice rose to such a volume that everyone in the tavern could hear him clearly,
"Friends...my companions and I count ourselves supremely lucky, not only to be alive, but to be surrounded by such charming folks as yourselves."
He slowly walks among the patrons nodding and greeting everyone as the murmur of the crowd began to fade. He begins anew
"We traveled far to seek the guidance of a recluse druid, only to find ourselves in the clutches of a fiendish wyvern and trapped by his treacherous acolytes! A few have requested a ballad be sung of this great tale. But friends...ballads are sung for heroes long lost, and we are not yet six feet under, so instead I offer you this jig!"
Jaskier slowly drums the table in front of hime rhythmically, eyeing those nearest him significantly until they understand and start to mimic the beat. Imbert, a little stiff, seems to a little off beat, but Zanben and Gwen seem to pick it up after a few tries. Jaskier gently puts his hands over Bandolor's to quiet him down who was making a loud, incongruous racket. He whispers "Sorry friend, we'll practice later, for now have another ale." Jaskier then pushes his two glasses, one with a small amount whiskey left, in front of him and pulls out a silver spoon from his pocket. He then begins to tap the the glasses with the spoon adding some harmonies to beat.

After a few turns with everyone keeping descent rhythm, Jaskier begins to sing the tale with Venomfang and their glorious victory. He finishes with a deep bow and then scoops up his glass to finish the whiskey and brings it back down on the table with a loud thud.
