I am on-loan from HMRC today.
Working on the 5th floor with the sheet music turned out to be rather productive.
Starting with row 227 I was able to get through 23 entries (ending at row 250).
With the add ins there were 8 that plopped into the spread sheet (rows 1288 to 1296).
That ended up with a grand total of 31.
The only real challenge was getting through the Michael Bolton music.
