This showband was a regular in Wick, Caithness (Scotland) in the 1960's.  Although there were many good local bands and many visiting rock and pop bands, nobody could draw the crowds like Maurice Lynch.  To read more about them and the rock and pop scene in Caithness at the time (it's very interesting - honest) visit Lynch & Co.

but if you don't want to bother, here's an excert :
"One week after the Yardbirds played Wick, twice as many punters packed the Assembly Rooms to welcome the Boys from Castle Blaney - The Maurice Lynch Showband was back in the Royal Burgh. A crowd of a thousand danced the conga, twisted and shook to chart hits, roared along the bawdy choruses of Seven Drunken Nights, and stood starryeyed with sentiment when Audie Heany sang My Prayer. A great night out, value for money, no-effort-necessary entertainment, unlike the previous week's act with their strange rhythms, their tortured, distorted guitar sounds. Thirty years down the road any self-respecting account of sixties music will mention The Yardbirds; abundant patience may be needed to discover references to Maurice Lynch & Co.”  
Does anyone know where they are now?
