Many of Harry's family members arrived at and attended his funeral including Olivia, but due to Earl's 8th birthday party, Harry couldn't go so Billy Joel went there for him. He was born August 4th and died July 24 at the age of 95 just a week before his 96th birthday (August 4).
On July 24 (the same day Harry's new baby sister Mia was born in the Park Plaza Hospital at 9:00am) and at 6:00pm, Howard complained of being sick to Journey singer Steve Perry's mom Mary Christina Queresma-Perry and her husband Marv, Harry's parents, brothers Sam and Danny, sisters Phoebe, Olivia and newborn Mia, aunts, uncles, grandaunts, granduncles and grandparents and music star friend Billy Joel, Amy's dad, sisters Molly and Jenny and grandma, Earl's grandpa and two of his older brothers Daniel and Mark, Stinky's mom and grandpa, Mr. Conrad's grandparents, parents, older brother Nick, younger sister Sherrie and brother's fiance Danielle and the Barnes family while in his nursing home and tried to get medicine but he didn't because he kept complaining of being woozy and not feeling well "I'm feeling woozy, I'm not feeling well, I'm feeling ill, I'm tired, I'm just sick, I'm not feeling very well. (groans)". He suddenly collapsed to the floor right in front of them and died of bronchopneumonia at the age of 95 just a week before his 96th birthday (August 4th). His family and friends gasped in shock, Danny cried "Oh my God!" and Olivia was so shocked she screamed in shock for her great-grandfather's sickness corpse! Billy Joel comforted Olivia and told her "Relax, Olivia. No need to get worked up, okay?". The next day before Earl's birthday, Harry received a phone call from his dad, younger sister Olivia and music star friend Billy Joel that his great-grandpa died of bronchopneumonia the day evening before and also he could not go to his funeral due to Earl's birthday party and all of his family members were attending it without him the next day so his music star friend Billy Joel filled in for him. On the day of Earl's 8th birthday party that morning, Stinky's mom and grandfather, Earl's grandfather and two of Earl's older brothers Daniel and Mark, Amy's dad, sisters Molly and Jenny and grandmother, also many of Harry's family members including his little sister Olivia, the music stars' families and the rest of the Barnes family (except Chucky Barnes who had his wicked pet snake Angriness killed by Harry's dog Spot and was arrested to jail for the rest of the summer vacation for bullying Harry and his friends and for kidnapping the Journey front-man Steve Perry's girlfriend Sherrie Swafford and trying to kill her. Wendy Wong and Mr. Conrad with his snake and his family members couldn't bail him out until the last day of summer vacation) attended Howard's funeral at Earl's Funeral house on a farm, but Harry couldn't go due to Earl's 8th birthday (July 26) at Earl's Journey Concert at the stadium so Billy Joel filled in for him. All of Harry's family members as well as Harry's friends' family members sang "Faithfully" by Journey to Harry's dead great-grandfather at his funeral while Joel played the piano. Harry despite not going to his great-grandpa's funeral due to Earl's 8th Journey birthday party talked his speech about his great-grandpa Howard before beginning Earl's 8th birthday party. He had also sang "I Miss You" to his great-grandpa who died of bronchopneumonia aged 95 a week before turning 96.
