Singer required for sixties band

We are a 60's Cover Band based in Keighley who have been going for approx 13 years and urgently require a new singer to front the band due to our original singer having to retire from the band because of work commitments.
The band consists of 4 other members, 2 Lead Guitarists, Bass Guitarist and Drummer.
Three of the band members are in there sixties and the fourth member is in his thirties.
Preferably we are looking for someone who doesn't have an ego and doesn't take themselves too seriously and would enjoy the fun of being in a band although band experience is not essential.
We do not play gigs every week but aim to play regularly throughout the year although this is always open to discussion.
We currently rehearse every 2 weeks at rehearsal studios in Keighley and like to make it a relaxed and fun night whilst taking the music seriously.
