At times at last night's Elvis Costello gig it felt that we had intruded on a jamming session.
The 48-year-old London-born, Liverpool-raised, Irish resident was at the National Stadium with The Imposters and it was only after two and a half hours, three encores and a standing ovation that he left the stage.
The man born as Declan MacManus was in great voice and loving every minute of the performance, though detractors could accuse him of being a bit on the self-indulgent side with his long heavy guitar solos.
Early on in the evening his monitor wasn't working and, after an acoustic interlude, the band took a break and came back on 10 minutes later and gave it everything.
Passion, emotion, and enthusiasm as always.
"It's good to be back home," he told a crowd of about 5,000 mostly in their 30s, 40s and 50s.
Much of the material in Costello's set came from his current album, entitled When I Was Cruel. However. he also dipped back into his 11 albums and 300-plus song catalogue for the evening's entertainment.
Favourites included "Indoor Fireworks," "Diving for Pearls" and "You Little Fool." Many of the hits he played were re-interpreted with a heavier rock edge.
There is no doubting Elvis Costello's wonderful talent and voice but he seemed last night to be a man indulging in a final fling of some sort.
