For most people advancing in years , old age is about donning a pair of comfy slippers and taking life at a steadier pace . However , one group of mischievous seventysomethings , the stars of a new series of Channel 5 show OAPs Behaving Badly , are determined to rage against the stereotype . Among those behaving badly is former popstar Lee Graham . The 75-year-old , who had a smash hit in 1968 with 'Little Arrows ' under his stage name 'Leapy Lee ' , is refusing to put his carousing days to bed . Scroll down for video . Give us a kiss ! One-time sixties pop star Lee 'Leapy Lee ' Graham admits growing old disgracefully with his Danish girlfriend Bettina , who he describes as 'very sexually active ' Living in Mallorca , Lee admits to sharing a saucy sex life with his much younger girlfriend Bettina , 49 . The couple make it clear in the show that they are still very much full of life , with Danish Bettina at one point presenting her lover with a penis pump after visiting a sex shop . Lee said : 'Tina is a very sexually active young lady , she is quite fit and she 's quite a big girl . She 's just a very healthy young lady and I 'm delighted to have her . ' I suppose you could meet ladies of your own age but 75 year old ladies are a lot different to 50 year old ladies . ' Lee admits to creaking bones but says his new lover has given him a fresh take on life . Singing to a different tune : Lee and Bettina argue over who has the most energy . She says her 75-year-old boyfriend is 'never tired ' Having fun ! Lee entertains locals in Mallorca with his old tunes and says : ' I think the game is to just , just make the most of it really ' He said : 'As far as age is concerned - I know that old cliché `` it 's just a number '' - but it is just a number is n't it really ? 'After meeting Bettina and everything it 's like a bit of a new lease of life . ' It seems that there 's life in the old dog yet . Bettina admits to often having trouble keeping up with her pension-age lover . She said : ' I 'm tired all the time he 's not . He 's almost never tired . ' Lee keeps busy by belting out his tunes to the ageing party animals in Spain and still has plenty of female admirers - something which turns Bettina green with envy . He said : 'Over the years I suppose I 've played to hundreds and hundreds and thousands of people , because I have been here thirty odd years . ' ' I think as far as the future is concerned when you get to my age what 's behind you gets longer and what 's in front of you gets shorter . ' I think the game is to just , just make the most of it really . 'And with Bettina 's help who knows . ' The series also follows the fortunes of other outrageous pensioners including swinging professor Colin and 'spiritual healer ' Raimondo , who is on the hunt for a younger lover . OAPs Behaving Badly is on Channel 5 at 9pm on Wednesday March 25 .
