The 61-year-old singer/songwriter and musician is bringing his latest album Good Feeling on tour to Glasgow's Royal Concert Hall on Wednesday, February 13.
The record follows on from the 2010 album A Different Hat which was recorded with the Philharmonic Orchestra.
"It's completely different," Paul says, "A Different Hat went off the beaten track a little bit, it was a labour of love and something I had wanted to do for a long time.
"It is recorded with the Royal Philharmonic Orchestra, but Good Feeling, which is the current album, is back to my bread and butter, my normal way of working and I think coming back to it now it has a freshness about it and it is because I took that hiatus."
Good Feeling lives up to its name as an upbeat album.
Paul said: "I never set out with a theme or a plan it just comes out as it is going to come out.
"As I say, coming back with this freshness and songs that work with my normal band in a live situation, I also had not a bad year, a lot of good things happened in my life.
"We had a grandson, my football team got promoted, my daughter graduated from college, there were some good things going on.
"For me it is a fairly upbeat record, I never sit down and plan any kind of concept or anything, it just comes out how it comes out."
With a career spanning four decades, Paul has written and performed countless tracks, but is probably still best known as the frontman of Ace, writing their big UK and US hit How Long?, singing lead on Squeeze's Tempted, and providing the lead vocals for Mike & The Mechanics' hit singles The Living Years and Over My Shoulder.
He's also written for The Eagles, Diana Ross and Tom Jones and has worked with legends including Roger Waters, Ringo Starr, Elton John and BB King.
He says there have been many highlights over the years.
However, he added: "I'm still waiting for my lucky break.
"I have a few trophies.
"We've been nominated for Grammy Awards and things like that, appeared on the wall live in Berlin - a quarter of a million people were there.
"A lot of ups and down, but this is my favourite time, doing what I am doing now.
"I think it is the most satisfying because it is about me, me, me.
"I'm the big cheese now in my little operation, and we play these theatres and people come and I get to sing all night."
Paul tours every year with his seven-strong band, which includes his son Jack, 24.
And as well as working on his own music, Paul is due to perform with the Eric Clapton band later this year.
The latest album is his 16th solo record and is released on his own record label Carrack UK, which he set up 13 years ago.
The near-title track Good Feelin', a song that lives up to its title if ever one did, has already become Paul's latest airplay favourite, and the album includes an irresistible collection of originals, including songs co-written with Squeeze's Chris Difford and songwriter Charlie Dore, and covers of Nick Lowe and Bruce Springsteen tracks.
Paul produced Good Feeling himself, and played most of the instruments on the album
He said: "My purpose is to enjoy what I am doing, I have had a great career, I have done a lot of different things, but it has been quite tough to survive this long, but I have survived and things are good for me in a lot of ways.
"I am more established as a solo artist and people still keep coming to see us, so my thoughts are I don't want any more pain from it, I just want to enjoy it.
"I enjoy my music, I have a great band, we are all good pals, we have a lot of fun, we have loyal fans who come to see us, so what is not to enjoy.
"Just stop worrying about it and enjoy it, that is my aim now.
"And the music has always been about basically just good vibes, good feelings and honesty.
"I don't have any political axe to grind or anything like that, it is not intellectual stuff.
"Hopefully it works on some kind of emotional level with some ups and downs but we like to send people home uplifted.
"It is soul music really, that is what it is, and I hope that people enjoy it, that is all it is meant to be - and it is the same with the concerts.
"Generally speaking people go out with a smile on their faces and feel they have felt something and experienced something and that is what it is about."
Paul has played in Glasgow many times before, including supporting The Eagles at Hampden Park
He said: "It is a great, great city.
"I think it is amazing, I think there is no where like it. It is just so alive.
"On the one had it is a bit scary, because if they are not going to dig it then you are in trouble, but usually they get beside us which is great - we don't take it for granted."
Paul Carrack will perform at the Glasgow Royal Concert Hall on Wednesday, February 13, at 7.30pm.
