AS That'll Be the Day celebrates its 21st year on the road and an unprecedented 10th consecutive Bournemouth summer season, the nation's most successful touring rock 'n' roll variety show has unveiled a brand-new look.

Despite its unique position performing as many as 230 shows a year to capacity audiences, the show's producer and director Trevor Payne has made the brave decision to totally rewrite the show.

It also has new sets, new lighting, new costumes... and a new cast member too.

It comes after last year's "greatest hits" tour when songs and comedy routines were selected from the past 20 years by the thousands of That'll Be the Day Fan Club members via the website.

Now it's a case of "out with the old and in with the new".

In fact, 80 of the 86 songs performed in the show have never been covered before.

While it is non-stop nostalgia all the way, the music styles are more diverse and now stretch from the '50s up to the '90s while staying true to its rock 'n' roll roots.

Trevor, who founded the show in the mid-80s and has performed in it ever since, told me: "Whereas previously we delved into archive stuff, this is the newest show we have ever done."

The catalyst has been the introduction of a new cast member - Rebel Dean, who replaces Morgan Turner, who has moved on to pursue a solo career.

Rebel has starred as Elvis in Bill Kenwright's production of Four Steps to Heaven in London and as Eddie Cochran in Rockin' On Heaven's Door.

He now opens That'll Be the Day as the young Elvis.

Trevor added: "I wanted to kick off with something fresh and Rebel joining us was instrumental in that. We have had no cast changes in five years.

"We have new material too and we've changed it all around and it feels like a completely different show.

"With so many fans coming to see the show regularly we wanted to give them something different."

There is an old adage, "If it ain't broke, don't fix it", so Trevor agrees this is a brave move.

"Even when Derek Block (the show's promoter) came to see the new production he said he felt scared.

"But the reason lots of acts fail and eventually disappear is because they don't have the courage to change.

"The great thing about Rebel is he's an impersonator as well as a singer.

"Rebel, for example, plays Shakin' Stevens to a tee. It's really uncanny and we've never included Shakin' Steven's before.

"That'll Be the Day is a variety show tucked into rock 'n' roll.

"A lot of people think variety is a dirty word today but audiences love it.

"The first half of the show has always been fairly chronological but the second half is a variety show in itself and all the cast members have moved on and are featured in a way they have not been featured before - they are firing on all cylinders.

"Mark does so much more in the show and Clive and Andy are doing more too and being stretched in new directions. The trouble is the genie is out of the bottle now! It will be interesting to see where we go from here."

That'll Be the Day plays the Pavilion Theatre until Saturday, September 16.
