I've seen 2 different dates for him dying...some say 4/1 and others say 3/31...
If it was 4/1 then it's a span of 5 months 2 days after his bday.
He died age 52.
Notice how he was also in the band called "Fever High"...

Of course he has a connection to Tom Hanks as well. He wrote the song "That Thing You Do" for the fictional band "The Wonders" in Tom Hanks film "That Thing You Do".
That Thing You Do=70
If he died on 3/31 it was 101 days before Hanks bday.
The film "That Thing You Do" also came out on 10/4 which reminds me of the Joker film coming out on that day too. I only mention this considering the connection to the word "Wayne" and Batman...Fountains of Wayne..
He died 186 days after the other founder of Fountains of Wayne's bday.
