There was news last week of an elderly jazz musician challenging the teenage pregnancy explosion by becoming a pension-aged dad.

However, he has followed the current trend of exotic, occasionally invented, names for the resulting hapless offspring.

The Leeds-based 63-year-old (I am bound to secrecy on his identity; a clue bottom right for those with local knowledge) has named his boy-child Thelonius, familiar to jazzers, but obscure to the general public. I wonder what they will call the boy in the playground? Answers on a postcard.

Wakefield Jazz re-opens tonight after the summer break, with the award-winning David Newton Trio. A great favourite in the North since his earliest days as a student at the Leeds College of Music, David brings with him Nigel Clark (guitar) and Paul Morgan (bass) in a tribute to the classic Oscar Peterson piano/guitar/bass trios. Phone 01977 680542 for details.

Tomorrow night Jazz in the Spa presents Jazz Connection, a lively and unrestrained group from the Netherlands. Jazz, jump, jive and swing, with a touch of rhythm and blues is the promise and you can see some band photos and hear a sample of the music at www.jazzconnection.nl The venue is the Trustees Hall, High Street, Boston Spa. Phone 01937 842544 for details.

York's happening jazz spot is the Jacobean Lodge, Plainville Lane, Wigginton (01904 762749), with Friday night piano jazz and a quartet on Sundays. The City's leading piano players jostle for position on Friday nights, so call the venue for an up-date.

The Sunday night acoustic jazz sessions have featured pianists Karl Mullen and Chris Moore and the tenor saxophone of Rob Lavers has alternated with the trombone of Andy Hillier.

Rob speeds to Wigginton, lip in hand, from his Sunday afternoon sessions at Kennedys Caf Bar, Little Stonegate (01904 620222). His Latin jazz sessions at Bobo Lobo are now every Wednesday (01904 621900), also on Little Stonegate.

Karl Mullen and Rob Lavers are turning into York's two-man jazz machine. They also have an alternating Tuesday residency with Nina Zagorski at the Last Drop Inn, Colliergate, York (01904 621951).

For a final word (just for the moment) on Rob Lavers, read the revue of the Manchester Jazz Festival in this month's Jazzwise magazine: "The post-bop Rob Lavers Quartet were a revelation, conjuring up a late 1960s session from Joe Henderson, they show great promise."

Belleville is a group dedicated to spreading a love of Gypsy jazz, the irrepressible swing style of the legendary Django Reinhardt. However, they are not content to copy and bring other influences of their bop heroes to push Parisian swing beyond its pre-WW2 form. Belleville will be the guest band at Scarborough Jazz on Tuesday.

There is great excitement in the pearl of the Yorkshire Coast for the impending Scarborough Jazz Festival, which will run from 15-17 September and is growing in esteem every year.

As well as big names, the festival commendably showcases the best of players in the region. Spot the familiar faces in the storming Big Band Byrne on Friday night at 7pm, followed by the acclaimed Bobby Wellins Quartet. The finale comes from Tina May with the Nikki Iles Trio with Scott Hamilton ("Hamilton has helped to redefine mainstream jazz for two decades" - Penguin Guide To Jazz on CD).

Saturday night's highlights will be Andy Panayi Quartet's take on the Gerry Mulligan songbook and Ian Shaw with Lianne Carroll, but my personal must-see will be Pete Oxley's Curious Paradise at 4.00pm. The featured saxophonist with Oxley will be Julian Nicholas, active on the York and Yorkshire scene in the 1980s when he was a student of English at the University of York. Subsequently, he went on to play with Loose Tubes amongst many others.

Sunday night headliners are Alan Barnes Quintet (Horace Silver tribute) and Georgie Fame with the Guy Barker Quartet.

Alan Barnes won the Best Instrumenatlist Award at the BBC Jazz Awards this year and will be the festival compere for the weekend, for the third year running.

Georgie Fame will be the closing highlight and festival organiser Mike Gordon says interest in this final concert is so great special posters for the event are mysteriously disappearing. Book now to avoid disappointment.

Pensioner dad clue: excessively hirsute banjo/saxophone player and raucous singer.
