And you would expect songs of such quality as Michelle, Yesterday and Penny Lane to endure.

Having seen several Beatles tributes bands what continues to surprise (and delight) me is the number of people in their 20s and 30s who seem to have a really great time listening and dancing to music that is more than 40 years old.

After all you can't imagine the young adults of the 1960s were having a great night out on Twenties music.

The answer is that at heart the Beatles were a great little rock and roll band- whatever the complaints from purists that they just played a watered down version of what went before them in the Fifties.

So when for an opener the Fab Beatles tore into one of the earliest Beatles numbers, the rock 'n' roller I Saw Her Standing There, the crowd at the packed Komedia were instantly up for a party.

Having seen a few Beatles tribute bands I think the Fab Beatles best capture the real heartbeat of the Beatles. They also have the finest imitations of the Lennon and McCartney voices and some great guitar work.

Standing in the Komedia crowd and listening to numbers like Tell Me Why it was easy to imagine the impact they must have had playing clubs like the Cavern.

The band also managed to capture those little distinctive licks and riffs on songs like Hard Day's Night and I Feel Fine that not everyone pulls off.

When it came to the tender moments, the band was not found wanting either. It was difficult not to feel a little nostalgic listening to the superb way they recreated In My Life, in my view one of the Beatles loveliest songs.

After the obligatory communal sing-along to Hey Jude the band and the crowd ripped into Twist and Shout as an encorre. Another sweet little rock and roller seemed just the right way to end this brilliant gig.
