The five members combine their talents as string players with mandolin, guitar, banjo, stand-up bass and fiddle and they all have great pipes as well.
Carrigan and guitarist Deborah Mackenzie are the band's songwriters and they have a number of songs about "caddish" male behaviour.
" You left the gate wide open with your drinking and your smoking" is a line from Carrigan's song Shut the Bloody Gate.
Despite recurring themes of errant male behaviour, fiddle player Krissy Jackson said all the band members are happily married to good men.
"Our Mr Diggitys don't behave like the men in the songs," she said.
There were songs of inspiration and celebration in the band's two-hour performance which got many audience members on the dance floor.
A woman's right to dress how she pleases is the theme of one of Mackenzie's songs Stop written with teenage daughters in mind.
"I don't like the way you're carin' what I'm wearin' what I'm sharin' what I got" goes the line.
Deborah Mackenzie's rendition of the Utah Phillips song Orphan Train could have been maudlin if not so beautifully sung and played.
A lone little girl on the dance floor added to the poignancy of the song.
The audience begged for more at the end of the performance and were rewarded with an a capella version of the lullaby Didn't Leave Nobody but the Baby from the film O Brother, where art thou.
I reckon everyone present was totally charmed by Hot Diggity - I sure was and I hope they come back soon.
